This bug has also been confirmed to occur on 1.88 and 1.89, but not 1.87.

Steps to Reproduce:

1. Open an untitled document and a webview panel next to it (for example, a markdown document and its markdown preview)
2. Right click in the untitled document, in the side bar or click an entry with a menu in the title bar
3. Observe that the webview panel becomes focused and the title bar entries jump over to the webview panel

Context:

In the VS Code extension for the Lean 4 programming language and theorem prover, we use a webview to provide additional information about the Lean document that the user is currently working on. We also use a title bar menu entry for all of our commands. The webview stealing the focus from the text document creates several very annoying issues while working on Lean documents:

• Right clicking an identifier in the Lean document and selecting "Go to Definition", "Find References" or "Show Call Hierarchy" will open documents in the tab group of the webview, not that of the editor, covering the webview and displaying the contents of the opened file in a panel that is typically smaller than the editor panel and probably too small to read code
• Right clicking to paste something in the search sidebar view and then clicking a search result entry will also shift the focus and open the document in the wrong pane
• When clicking the title bar menu entry, the entry suddenly shifts away underneath the cursor to the webview panel, which is very disorientating
