Project
Create a note, add three grace notes in front. Select all, add slur -> no result. Click on first grace note, add a slur. It connects to only the next note. Shift+right arrow does nothing, dragging does nothing.
If there is only one grace note I can properly connect it to the main note. If there are two, I can connect each other, but not to the main. If there are three, there is no way to do it even vaguely correctly.

You can put the slur in edit mode and press shift+right arrow to extend the slur, but of course you shouldn't need to.

I was wrong, the work around is to select the first grace note and ctrl+click the main note to apply the proper slur. I was pressing ctrl in my previous test.

Wow, hey, never even knew that was an option. Was always shift or selection +s for me. Thanks!
Ctrl+click doesn't work really either, it just pretends to, visually
Can you explain what you mean when you say it just pretends to work? Seems to work for me in the ways I expect...
Doesn't change the anchor
Doesn't it? Seems to for me. What makes it seem otherwise?
Zoom in, double click slur, select the handles
Ctrl left/right is not changing anchors and never did, it just moves a handle by 1sp
That's what I'm doing, and it looks fine to me. If I drag a handle, I can see the dotted line going where I expect. Hard to get a good screenshot...

You can see the red circle for the anchor is closer to main note. I used ctrl+left arrow to move the end out of the way. I also move the grace notes to make it clearer.
So, to be clear: Ctrl+click the start and end note followed by pressing "S" or double-clicking the slur icon in the palette is a workaround, not just pretend. Not necessarily the most obvious, as this technique probably isn't used much (it's also useful for cross-voice or cross-staff slurs, btw). But, the difference between the workaround being real versus pretend is the difference between P1 and P2 for me on this particular matter.
click 1st note, ctrl+click last notes, hit "S", that is the workaround, as I've now learned...
I think this issue might've been stealth-fixed? Slurs on grace notes are working for me in MuseScoreNightly-2018-12-08-0922-master-a9203cb.
How so? The Cltr+click method works as noted above (click first note, Ctrl+click second, then press "S" or double-click slur in palette). And single grace notes work fine. But I don't see other way with multiple grace notes. In particular, clicking the first grace note, pressing S, then using Shift+right doesn't, nor does click first grace then Shift+click the second.
Shift + right arrow worked fine for me on the current nightly.
Odd, for me not, but my build is maybe a few hours older. Didn't think were any relevant changes though.

Doesn't work on OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 3.0.0.4346, revision: a9203cb
Not fixed for me either, latest master, Windows 7
I missed the proposed workaround. Thank you @Marc (https://musescore.org/en/node/279131#comment-874009).

Same problem. Can't extend or shorten slurs on grace notes by shift + R/L arrow.

If it is the case in 2.3.2, there is no regression.
The command works in 2.3.2, so it is a regression.
Above you claimed to have the problem in 2.3.2
Oops. I've corrected the post.
Came up again in https://musescore.org/en/node/286851
BTW, this isn't a regression it's been that way at least since 2.0.3.
2.3.2 definitely allowed slurs involving grace notes to be extended via Shift+left/right, so this is a regression. I can see the code changes that resulted in this not working any more, and I am working on reinstating it.
