So FWIW there is a Dell 2-in-1 that has been conflated into this same issue.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1822394

Something that is confusing to me is that on the Windows side all these
machines use the same Intel driver for this infrastructure no matter the
OEM.
So they can't possibly be putting in quirk specific stuff in the driver side
can they?

It has to make you wonder if some baseline assumptions made in the
driver early on around tablet mode support are completely false.
