I agree that this behavior is insane and should be fixed.
Do however note that it is possible to install another keyboard on iOS, which may alleviate your suffering before you switch to Android in about 120 days.
Personally I rely on Gboard [0] every day for the simple reason that it auto-detects several (more than two) languages, and of course it has the added benefit of not having this crazy bug. Gboard is google software however, so it does come with huge privacy issues, and others will hopefully point out better alternatives.
Any properly supported third-party keyboards? Swiftkey was bought by Microsoft and lost my vote. Gboard stopped updating.
I have Gboard and have weird issues with it crashing randomly. Not sure if it's because it's hamstrung by the limitations of Apple's support for alternative keyboards or what.

I do the same, and I find it way better.
Gboard is a lot better than the native keyboard. Strange that OP is going to such lengths to complain when iOS supports other keyboards.
The main benefit I've found with Gboard is a larger vocabulary, and perhaps a less aggressive autocorrect that doesn't constantly try to correct technical terms into similar common words.
Gboard for iOS has been discontinued though. On top of that, 3rd party keyboards are a bit limited on iOS (which might be a good thing for some people).
