https://searchfox.org/firefox-main/rev/202150dcdade5798ca858b843b51b20112b4d061/browser/themes/shared/tabbrowser/tabs.css#610 adds a box shadow on .tab-icon-overlay in all cases with Nova enabled. That works well for the audio and tab notes overlays that bring their own rounded background, but for a crashed tab, the shadow appears as a box. The box-shadow should probably only be applied when the tab is not crashed.

Screenshot shows vertical collapsed and horizontal tabs, simulated by adding [crashed] to the <tab>. However, I saw this with a real crashed tab, which can be reproduced by navigating to about:crashcontent.

Current behavior

The crashed tab icon has a square shadow

Expected behavior

The crashed tab icon should not have a shadow
