A few tiny concerns to resolve:

1. • Bug: The WYSIWYG editor has 3 toolbars with old styling on load which become 2 toolbars with the new styling. May we have it directly load with 2 toolbars with the new styling? : https://www.loom.com/share/98110feca6b94b3a92424dec82f61ab5
2. • Enhancement: The Enter Key on the keyboard should trigger the Save Button on the Resize Image Modal
3. • Bug: Make the width and height inputs only support numeric values. They should not accept special characters or alphabets.
4. See Loom video for requests 2 and 3: https://www.loom.com/share/f0e3f7a4124742629aa295d17d8eaa58?from_recorder=1&focus_title=1

@theofficialnar I'm seeing performance issues with typing. It is slow to show the characters as a I type them.

List text styling differs from body copy. This seems unintentional.

@shrunyan this seems to be what we've discussed a while back with all of the field components re-rendering every time a user types, causing the lag. This is specially noticeable on content items with lots of fields, I see this happen even on prod as well. Do you reckon this is something worth fixing on this project or in a new one as I think the solution to this involves some major component re-composition and is not specific to the tinymce editor since all other input fields lag as well.

@theofficialnar I retested and see as you've explained this performance concern being present across environments. With that being the case not lets not hold up this body of work. Please do prioritize fixing the performance concerns but do so on a separate branch.
