I don't know if this might be a parser issue or a devtools issue. This doesn't look like a security issue, so I'm going to unhide it.

Not a security problem in any case.
If three completely different browser engines agree you should check your understanding before assuming they all got it wrong. This is the way HTML and the HTML parser are defined. For example, <h1> cannot be inside a <p>, so encountering one implies a missing </p>. Likewise, encountering a nonsensical un-started closing tag causes the insertion of the matching start tag. Please see the specification.
