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