We don't suppress "is" right now. So the recommended pattern is to use "as" and if you really need to, do a null check afterwards. Either way, I thought "is" and "as" would "just work" with HTMLElements. There is an "instanceof" check in the code that should work. The @flexjsignorecoercion is mainly an optimization to suppress code you pretty much know is going to work. However, it looks like it may not be safe to test against HTMLInputElements.
