As the issue tag states, this needs tests to be committed.

The approach proposed here does not handle well the situation of nested IEFs, when Cancel is pressed on the parent IEF. This is because of inline_entity_form_close_all_forms() I think, that function seems to override what this patch does.

I don't grok it fully but maybe you can describe the exact steps that uncover the problem you describe, the chances that your objection gets into the tests drastically increase.

Re #20 from memory:
1. Sitebuilder: Nest once complex IEF inside another
2. Sitebuilder: Set the inner one to auto open
3. User: Open an entity in the outer IEF; SUCCESS the inner IEF auto opens properly.
4. User: Cancel the opened outer IEF
5. User Open the same entity again in the outer IEF; FAILURE the inner IEF does not auto open now!

I closed ✨ Expand inline entity form widget setting Closed: duplicate as a duplicate. I'm granting credit to @vyasamit2007 and @rhovland for work done on a patch in that issue. But the patch was fairly similar. I don't know that there's anything that would be useful from it.

Everyone please remember to check for existing issues before opening a new one. Today I've closed two issues that were older than this one.
