#33617: Visual Editor freezing when I add multiple HTML tables to the post

 Ever since I updated my website to 4.3 my visual editor is freezing every
 time I try to highlight a piece of text, or even place my cursor someplace
 random. This only seems to be happening on the text contained within a
 HTML table, especially when you have multiple tables below each other.
 When I open console tab in Chrome, following error is displayed over and
 over again:


 {{{
 Uncaught RangeError: Maximum call stack size exceeded --
 tinymce.min.js?ver=4203-20150730:7
 }}}

 I tried disabling all of my addons and changing my theme. Also installed a
 fresh copy of WordPress on a sub-domain, and on a local XAMPP server.
 Happened every time, and seems to only be related to 4.3. - since
 everything works fine on a 4.2.3 website that I still haven't updated.

 To replicate this error, copy the HTML table code bellow and paste it
 couple of times in a new post - around ten or so, enough so that you can
 actually scroll the page a good amount. Then try scrolling the page in the
 Visual Editor with your mouse-wheel and while doing so try to select a
 piece of text. This without exception freezes my screen for good 4-5
 seconds. Might not happen right away, but just keep scrolling up and down,
 and click your cursor on random places withing those tables.
