Using reserved words as intrinsic elements in TSX

[erikbrinkman]

Bug Report

Using a reserved word as the name of an intrinsic element triggers the error Identifier expected. '<word>' is a reserved word in strict mode.. This is similar to #17452.

I'm happy to submit a PR, but I am not familiar with this path, so I'd need guidance on where to look / what to consider.

🙂 Expected behavior

no error since ultimately intrinsic elements become static strings or stay in jsx format
