Repro steps:
0. Make sure the details sidebar is collapsed in the Search Tab and visible in the Elements Tab. Also ensure the Experimental `Show Independent Styles sidebar` option is enabled.
1. Open a new window to `webkit.org`.
2. Inspect the page and perform a global search (Shift+Command+F) for `webkit`.
3. Select one of the DOM node entries for an element (has a Purple square with the letter E for an icon).

This issue does not seem to happen when the experimental option is disabled, or if the sidebar was visible in the Search Tab before selecting the DOM node element entry.
