Typed-in text is doubled in Play mode in a UI element

When I type text into the editor, say the Hierarchy search, text appears as you would expect.
But when I type text into a UI element in Play mode, all characters are duplicated.
e.g. I type abcdefg, the field shows aabbccddeeffgg

See the attached screenshot; the UI element is at the very bottom.

Very happy to see the editor in Linux. Thank you.

Confirmed, fixed for next build.

Cool, thanks for the effort.

Yes, thank you very much!
