>Exactly, the unclosed I tag is the reason I wouldn't bet on anything here. Any browser may decide to automatically close it on the next piece of markup, and have its own rules on what it
considers one. Or it may not close it until end of paragraph (again, with its own rules as to what makes an end of paragraph).

Yes, correct, this is why I brought the point. I was trying to collect information as to know if there is something generic that can be done on some isolated cases. But, it seems to turn out, this is browser level decision to act upon such situation or not.

Thanks
