Details

STR:

  • open data:text/html,<iframe src="data:text/html,<style>* {color:red;}</style>"></iframe><button onclick="document.querySelector('iframe').remove()">remove</button>
  • click on remove remove which removes the iframe having stylesheets

Current behavior is that the stylesheet of the iframe is kept displayed in the style editor and can only throw.

Ideally, we would remove iframe stylesheets when theirs iframe/document is removed.

Note that adding an iframe while devtools is opened works fine.

I can easily repro on my machine.

Thank you for the report Alex.
