Glissando text change lost if placed in a palette and on Save-Reload

3.0.5 / Windows7

1) Default score, or load the test file: glis.mscz
2) Add two notes and a glissando
3) In Inspector, change the text, e.g. "slide" (common in electric guitar) instead the default "gliss."
4) Drag and drop this glissando/slide in a palette

Result: as expected, but if you add again the "new" symbol on another place/note, the text "Slide" is lost (it reverts for gliss.) - image below.

5) Save/Quit/Reload

Result: the text is now also lost in the palette.
