Problem or use case

When a web preview is open in the right sidebar, there is no way to zoom its content. The pane is narrow, so pages built for full-width viewports render small and are frequently unreadable. Cmd +/- either does nothing there or only affects the app UI, not the embedded page.

Proposal

Support zooming the preview webview: Cmd +/-/0 while the preview pane is focused, and/or a small zoom control in the preview toolbar. Persisting the zoom level per preview session would be a bonus.

#3893 asked for wider side panel sizes (closed); #4627 covers UI zoom on the sidebar/main view. This request is specifically about the content of the embedded browser pane.

Closing: current main already covers this as of 52c77c1ec4. If you still see it on a build that includes that commit, reply and we'll reopen.
