It seems a variety of menu items are now dead; including the "Menu -> Help -> * functions.

Right-clicking after selecting text also fails to post the normal UI menu, which may be related??

None of the items on the "three dots" menu appear to work, and the bug appears to affect both versions 0.19.106 and 0.19.107.

Yup, it looks like something regressed with the C63 builds... Possibly related to #12185 and #12175.
