[khmer_angkor] bug: Long press on the spacebar key shows blank subkey in Khmer Angkor Keyboard

[bharanidharanj]

Describe the bug

I noticed that an empty subkey appears over the spacebar key, after long pressing the spacebar key.

Reproduce the bug

1. Install Keyman 17.0.110-alpha build.
2. Open Keyman In-App.
3. Download and Install Khmer Angkor Keyboard.
4. Switch to Khmer Angkor keyboard.
5. Long press the Spacebar key.

Here, I noticed that a blank subkey appears over the spacebar key. I did not see the same behavior when I use the default EuroLatin (SIL) keyboard.

I have attached the video file for reference.

Note: Able to reproduce it in previous version of keyman 17.0.98-alpha build.

Expected behavior

Long press on the space bar key should not show any empty subkey on the keyboard.

This is a design issue with the Khmer Angkor keyboard -- longpress is supposed to give you a space whereas a short press on the spacebar inserts a zero-width space. However, as you point out, it isn't clear. Perhaps we should be labelling them?

Moving to keyboards repo.

Just noting in 17.0, the OSK can also use key text:
*Sp* for regular space and
*ZWSp* for zero-width space
