[BUG] Holding down certain keys stalls the message thread

Not sure what to make of this one. In reaper on windows, if you click anywhere on a juce gui, so the component peer eventually grabs keyboard focus, holding down certain keys, such as the ‘a’ key, will stall the message thread. If you edit a label so it actually eats those a’s, that’s fine.

Anyone else seeing this in their projects?
