Description
Updated to 1.8.9 and menu's are not scaled with the Interface scaling setting.
The text in the editor is scaling, but not the menus.
Setting the GDL_SCALE environment variable doesn't work either.
Here's a screenshot comparing the menus from kwrite with arduino editor.

Research direction
No source files, tests, or entry points are named in the issue. First reproduce the behavior on Linux in Arduino IDE 1.8.9 with Interface scaling and GDL_SCALE, then compare editor text and menu scaling; done means the menus scale consistently with the editor.
