fatal error involving infinite recursive transclusion of edit template

[mgroth0]

I tried to debug this myself quite a bit but fell short of understanding the dev tools and being able to investigate further.

• The outermost issue is that all of a sudden my wiki got the error Uncaught TypeError: Cannot read property 'document' of undefined which made my wiki unresponsive.
• I determined the source of the issue involved a transclusion of the text of draft of $:/core/ui/EditTemplate (paradoxical, I know. I should not have tried to edit that inside my wiki.)
• The exact location of the error was $:/core/modules/editor/engines/iframed.js line 36 this.iframeDoc = this.iframeNode.contentWindow.document;
• This was due to this.iframeNode.contentWindow being undefined
• Now I am new to all of this, but this was just a great learning opportunity. My goal was to compare how this.iframeNode is constructed in my wiki vs tiddlywiki.com, and this is where I get confused. I tried to "step into" the createElement("iframe") function that precedes the error by 2 lines. -- In my wiki, this brings me to line 278 of TiddlyWiki5/core/modules/utils/fakedom.js return new TW_Element(tag); -- In tiddlywiki.com, Chrome dev tools just jumps right over this function even when I use "step into".

So that's the moment when I called it and gave up. My main question is this: Why can't I step into createElement("iframe") in tiddlywiki.com? You can see for yourself by putting a breakpoint on the lines I mentioned and editing any tiddler.

I've encounter this too, I'm trying to use

{{$:/state/Calendar/PageLayout/create-tiddler||$:/core/ui/EditTemplate/body}}

in a modal created by

new TWModal($tw.wiki).display('$:/plugins/linonetwo/tw-calendar/calendar-widget/tiddlywiki-ui/CreateNewTiddlerPopup', { maskClosable: true });

I think in a modal, something is different...

step into createElement("iframe")

This is a browser api, you can't step into it.

This bug happened when edit-text widget has toolbar.

Thanks @linonetwo can you show a minimal test case to reproduce the error on tiddlywiki.com?
