How can removing prove content independence? Does content replacing change anything? No it doesn't. So this is not content dependent.
I don't recall another instance of this being reported, so the risk is low.
Not quite. It's 100% repeatable if you have 2 head placeholders on the page in the multipage document that has head placeholders on multiple pages.
As asked before, could there also be a link with having the favicon <head> placeholder set as a 'repeating object' across multiple (different sized) pages (rather than just manually duplicated)?
No. This is not it.
After it's fixed, having got used to the work-around, the fix may be redundant
True, true...
