I can reproduce it with 4.10.0 too.

Something interesting I found is that if you focus into the ckeditor before focusing into the number input, the error doesn't pop up

Anything happening with this issue?

Hello there,

I can confirm this is also happening with the version 4.5.10 in Firefox 64.0.2 (64 bits) on Mac.

Please add "👍" reaction to the first post, that better helps us to understand how often the issue is faced by our community. Thanks.

I can confirm a bug. When ckeditor has divarea plugin and You focus on an input field with type number, error occurs. I have windows 10 with FireFox 66.
I'm using it with angular 7.2

The issue is caused by Firefox itself. window.getSelection results in invalid range containers when used with the active number input element. I already reported the upstream issue on Firefox issue tracker, please subscribe https://bugzilla.mozilla.org/show_bug.cgi?id=1563739 for more details about its state.

From my perspective, the issue is not causing any serious problem except console error, so there is no need for any workaround. However, if you notice some issues with your browser application or CKEditor itself, please, let us know so we can reopen this issue and consider a solution.

This does actually cause issues, it prevents you closing some dialogue boxes.

It's happening to me a lot when trying to open HTML video, you get the dialogue, change something, then click OK and nothing happens but it does keep adding errors to the console.
