Uncaught RangeError: Maximum call stack size exceeded with custom Elements

[yannkost]

Describe the bug

After upgrading from version 3.43.0 to the actual version 3.53.1 I had to revert back as my webcomponents (which can contain a lot of conditional rendering/lot's of HTML/combinations with other webcomponents) often can't render with following error:

I also saw that this error only occurs in Chrome and not in Firefox, so I'm at a loss here. I have seen some similar bugs in the issues, but I don't really know what the fix should be. I will try to make a reproduction but it won't be easy as my components rely on another project that is intern to our company and can't be published.

I think this is a issue with the 'inifinite loop of flush'?

Sounds like #7032 (https://github.com/sveltejs/svelte/search?q=Maximum+call+stack+size+exceeded&type=issues), which fits your version range. You can verify by checking that it breaks between 3.44.2 and 3.44.3. If it does, then it's probably a duplicate.

@Prinzhorn yeah I just tested it, indeed this breaks between 3.44.2 and 3.44.3, sadly a dealbreaker for me as I can't update svelte like this... (and not use the latest version of the vite-svelte plugin...) so #7032 is indeed the problem/solution, hope this get's fixed fast. The solution seems to be ready for over a year already?

Closing as duplicate of #7032.
