Assigning a letter key to a shortcut sometimes puts the letter in the next dialog

[robchafer@…]

What steps will reproduce the problem?

1. Assign a shortcut to Toolbar/Water/Water of the key L
2. Mark an area
3. Press L

What is the expected result?

The Change 1 object dialog appears with Water body set to water and name blank

What happens instead?

Sometimes... the Name part of the dialog gets filled with the L (lowercase)

Please provide any additional information below. Attach a screenshot if possible.

This doesn't happen every time, maybe 1 in 5. It is as if the keystroke is carried over into the
dialog. Interestingly if I hold the 'L' longer than normal it rarely appears in the Name field.
I definitely do not press the L key twice.

Wow, what a faff that was. Anyway.... now on 1.8.0_251 and it seems quicker!

The issue is still there but much less so -- maybe one in 30 instead of one in five. I can live with 1 in 30.

@team: anyone wants to investigate further, or close as worksforme/irreproducible?

[Klumbumbus]

I just noticed that I can reproduce this behavior :O

[robchafer@…]

Excellent!

[taylor.smock]

Is this still reproducible?

The only way I was able to reproduce (Mac) was by holding l down. Which brings us into the territory of OS designed feature.
