Changes between Initial Version and Version 1 of Ticket #47218, comment 18

initial	v1
1	1	See this plugin, which is getting pretty close: https://github.com/ClassicPress-research/ClassicPress-Editor
2	2	I tested it yesterday in WP 5.2 and it worked (Classic block), although I had to use a `define` so it loaded correctly.
	3	Edit: I just want to add that 5.x isn't distinguishably better, and the internal changes are large enough that the security issues were from 5.x, not from 4.x (that's just a guess). I was testing the a11y yesterday and it seems the toolbar is less accessible than before.
