Despite many attempts I could not reproduce this issue. I have tested this on Edge version 20.10240.16384.0 Could you tell me:

1. Which Edge version you use?
2. Have you got any custom add-ons or Edge plugins installed that could influence this problem?
3. Could you try reproducing this issue on CKEditor nightly - ​http://nightly.ckeditor.com/15-12-03-07-07/full/samples/ (Since I could not reproduce this issue and you could, I don’t think this is it, but please check it anyway). Please don’t forget to Clear Browser’s cache when doing so (this is not Ctrl+F65 which is cache refresh) - ​https://kb.iu.edu/d/ahic
