Bug report: panel icons are partly hidden after customizing the icon bar

panel icons are partly hidden after customizing the icon bar:

Resizing the panel vertically will fix the bug, nothing else I tried will.

EDIT: Scratch that last comment.
I cannot fix the panel icon bar without terminating Rhino :frowning:

Here is what it looks like (simply add or remove any of the functions in the icon bar will leave the refreshed icon bar like this):

If you drag the inspector container width, the icons are re-centered.

RH-59421 is fixed in the latest Service Release Candidate
