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

[dankop]

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.

Hi @dankop, thanks for the bug report.

Confirmed in both Firefox and Chrome. Not caused by our custom plugins, happens in the TinyMCE demo: ​http://www.tinymce.com/tryit/basic.php (use Tools => Source code to paste the test html). Passing upstream for further investigation.

Alright, thanks for the swift feedback!

This actually was fixed upstream couple of days ago: ​https://github.com/tinymce/tinymce/commit/431bf04da54599239cb1577dcff75032c6897855. Will be in the next TinyMCE update.

That's very good to know, thanks! Hoping for a quick patch then.

Consider for fixing in 4.3.1. Needs TinyMCE to be updated to at least 4.2.5.

Fixed in r34029.
