iFrame gets refreshed despite data-reflex-permanent

[RolandStuder]

Bug Report

In some cases iframes get refreshed when they shouldn't. This happens when sibling nodes get added / removed to a parent element of an iframe.

• The content is respected not change, but some aspect of the element/node is touched which makes the iframe reload. See last minute of the video below.

Might be this issue here: https://github.com/patrick-steele-idem/morphdom/issues/200

I've been working on this about 40 hours now, and I've sadly made zero real progress. I've asked for help from @snewcomer but he's likely very busy with @snewcomer things. This might just need to be documented as a warning so that I can move on with my life.

@RolandStuder I think we should close this because it's an issue that can only be fixed in morphdom. 😿

I'm going to attempt to add something about this to the docs: https://docs.stimulusreflex.com/appendices/troubleshooting#iframe-gets-refreshed-despite-data-reflex-permanent
