Why is a form field auto-populating with a space/dot/dash?

I'm noticing an extremely weird behavior where form fields are getting auto-populated with a space or a dot or a dash. I've attached the pictures. It's pretty much making the browser unusable with several websites.

Version: 62.0.3331.43

What I've tried/verified so far?

1. It does not happen on other browsers. But I'd like to continue using Opera browser as it feels faster than others.
2. Cleared all form-auto-fill data. No use.
3. I've not installed any add-ons.

This is what happened the moment I clicked on "New Topic" button on this forums page.
