Thank you for the report, wolnewilno@gmail.com. I can reproduce with html.html.

Based on the trace (attached), this freeze is a result of a work that's not accounted for. I am going to guess it's the language detection, but it's hard to tell without digging deeper.

+joelhockey, since it might be relevant to Web Agents work.
Errr. trace attached.

Example URL changed so use html.html to reproduce
Chrome version 63.0.3239.132 and still active after more than 2 months from start. If you will add more forms make longer freezes. It's freezing after any DOM manipulation (even changing in CSS visibility in other elements) but it not existing in above example (html.html) because it's pure HTML for better understand problem
