Snippet demonstrating the behaviour

I have a Tab Folder (see the snippet attached) with a toolbar and some textfield and everything looks fine.

Now I update the toolbar on button click, now the whole control in the tab gets shrink and stretched outside the view .

Now I resize the window and/or move the sash a little bit the control gets back its full height.

Move the sash back and forth more and more restores the initial appearance.

Clicking the button again destroys the layout again.


This happens under Linux gtk3 + windows 10

Which Eclipse version is used? 4.20 master? Is this a regression?

I see this with Eclipse 2021-03 release in my RCP app and tried the snippet with the current platform-master.

I don't know if it is a regression (the tab folder was just introduced recently in my UI).

FWIW: also reproducible on Mac.

Appears to be a regression; doesn't occur with a Neon.3 baseline.
