[BUG] - Bookmark is wrongly deleted while using Backspace one line below

[shp7724]

Similar to #424.

Environment/version

• Extension version: 13.2.2
• VSCode version: code-server 3.12.0
• OS version: macOS 12.0.1

Steps to reproduce

1. Create a bookmark at the end of the line.
2. Type Enter.
3. Type Backspace.

Hello.

First of all, please note that I'm not using native vscode, which might be the cause of the issue. All other features of Bookmarks work just as expected, however.

I recorded what's happening when I type backspace to move to the line where bookmark was created.

Please let me know if this is expected behavior, or reproducible in the native vscode.

Update

Seems like it has to do with the experimental sticky engine, which was enabled by default. After disabling it, the bug is gone.

Thank you.

Is this issue planned to be fixed? This issue is critical for my use case, and I wonder if it isn't for other people. 😢

I've got a similar problem. Steps to reproduce:

1. Create a bookmark
2. Go to the end of the line
3. Press 'Delete' key
4. Bookmark will disappear. E.g. for PHP:

I had disabled all extensions except Bookmarks before an experiment.

Disabling sticky engine really helped.
