In Firefox, tooltips in the file explorer and editor tabs do not disppear

[ading2210]

If you use Firefox with the web version of VSCode and hover over files in the explorer pane or tabs in the editors, the tooltips do not disappear once you move your mouse away.

This was first reported as coder/code-server#6719 but it seems that it is really an upstream problem.

To reproduce:

1. Open https://vscode.dev/github/microsoft/vscode in Firefox
2. Move your mouse over the files in the file list and observe that the tooltip doesn't disappear once you move your mouse away
3. Open a few tabs and click on one of them. Move your mouse away and observe that the tooltip for the tab does not disappear.

Workaround

Setting these options prevents the issue from occurring, but the tooltips don't appear consistently.

{
    "workbench.sash.hoverDelay": 0,
    "workbench.hover.delay": 0
}

To add to this: It would be nice to be able to turn them off all together. I posted details about this over on code-server’s GitHub page: coder/code-server#7816 (comment)
