Bug: languagetool's chromium extension css overgenerated in the document

This is a follow-up to my report months ago in google extensions site, here is three screen shots of the language tool generating dozens of style nodes to a document on each click and scroll over a text box in chromium.

As I cannot post more than one picture I hope this picture highlights the problem clearly enough :slight_smile:

Thanks for the report. We’re currently making larger changes to the add-on, so I hope this will be solved just by those changes.
