bug(web): Longpress on spacebar gives a very wide longpress menu which looks rather strange

[bharanidharanj]

Describe the bug

While long pressing the Spacebar key in the Khmer Angkor keyboard, there is an extra (without caption) space bar appears over the actual keyboard.

Reproduce the bug

1. Install Keyman 17.0.13 Alpha build.
2. Open Keyman In-app.
3. Verify EuroLatin (SIL) Keyboard appears as the default keyboard.
4. Long press any letters in the Keyboard.
5. Verify the long press key of any letter works.
6. Long press Space bar key.
7. Verify no it does not show up anything.
8. Download and install Khmer Angkor Keyboard.
9. Switch to Khmer Angkor Keyboard.
10. Long press the Space bar key.

Here, I noticed that an extra spacebar key appears upon the actual spacebar key. Seems to be an issue.

Expected behavior

1. While long pressing the Spacebar key, it should not show up another empty keyboard over the actual keyboard. (in Khmer Angkor Keyboard)

This is actually by design (even if perhaps not 'great' design!) -- a longpress on the spacebar allows you to insert a real space; the default is to insert a zero-width space.

Two things I can see here:

1. What is shown on the longpress is unintuitive (an issue with Khmer Angkor keyboard @MakaraSok?)
2. The very-wide longpress key looks strange (a design issue for KeymanWeb)

@mcdurdin Tested the same scenario with Android emulator and I noticed that it shows an empty key while long pressing the space bar key.

It might be good to change the Khmer Angkor keyboard to show 'space' or Khmer equivalent on that key?

On my Android device, longpressing the spacebar causes all keys encoded for longpress on spacebar to appear in cells the full width of the spacebar. It would be preferable if they appeared in cells of ordinary width (as shown in the image shared by @bharanidharanj.)

May I suggest making it possible to specify the width of a longpress key in like fashion (i.e. with the same code) as one can specify the width of an ordinary key?
