ProWriting Aid Corrupting Editor

I noticed that the grammar/style checker ProWriting Aid extension for major browsers (Chrome, Edge, Firefox) corrupts most of the post editor on

I found I could only write about 4 lines before my text started disappearing offscreen.

I disabled the ProWriting Aid extension in all my browsers and the editor returned to normal in each of them.

I don’t know if it’s the extension that’s bad or some sort of conflict with the editor.

It did not corrupt the Wordpress or Medium web editors, so I thought there might be a connection.

But thought I’d mention it.
