Is there an existing issue for this?

• I have searched the existing issues

OS/Web Information

• Web Browser: Firefox 115 ESR
• Local OS: Debian 12
• Remote OS: Debian 12
• Remote Architecture: amd64
• code-server --version:

1.87.0
e5d145fdf32e82be2a0f8de9a3b05f65b13052b6
x64

Steps to Reproduce

1. Open code-server in Firefox
2. Move your mouse over the file explorer, tab bar or extensions list
3. Move your mouse to the text editor

Expected

The tooltips inside the file explorer/tab bar should disappear once the cursor has been moved away from them.

Actual

The tooltips remain until some other pane gets focused, rather than disappearing when the mouse is moved away.

Does this issue happen in VS Code or GitHub Codespaces?

• I tested this in native VS Code.
• This does not happen in native VS Code.
• I tested this in GitHub Codespaces.
• This does not happen in GitHub Codespaces.

Are you accessing code-server over a secure context?

• I am using a secure context.

Notes

This issue does not occur in Chromium-based browsers such as Brave.

This issue did not occur in an older version of code-server which I recently updated from.

[code-asher]

Could you confirm whether the behavior occurs on Codespaces and/or vscode.dev as well? This very well could be an upstream issue.

[code-asher]

Actually nevermind, I just tried and it does not reproduce in Codespaces.

Weirdly, the tooltips there do not seem to obey the theme, so I guess they are native tooltips? But code-server is using non-native tooltips for some reason?

Issue also happens in vscode.dev
