Changing priority

This is just a guess, but I think that MuseScore is following a rule from Elaine Gould's "Behind Bars". It's the music notation handbook from which many of MuseScore's notation rules were drawn.

Here is what Elaine Gould says on p.309 in the paragraphs on Fingering in the Keyboard section:

"The general principle is to place fingering as close to the notes as possible in the relevant notes: directly above or below, in front or even after them."

On the other hand, the illustration on that page shows the fingering further from the note than the slurs in some cases, so maybe the same should apply to accents? I would be interested to know what others think.
