Adding a comment on a page enables Watch even though Autowatch is disabled

Issue Summary

Even though I've disabled Email Settings -> Autowatch, Confluence Cloud still automatically watches pages that I comment on.

Description of this setting: "Pages and blog posts that you create, edit or comment on will automatically be watched for future changes." ..so I expect that commenting shouldn't trigger auto-watch when this setting is disabled.

This is reproducible on Data Center: Not sure

Steps to Reproduce

1. Unwatch a page
2. Comment on it
3. Page gets re-watched automatically

Expected Results

(3) should be n/a, i.e. Watch status should change as a result of commenting

Actual Results

(3) as stated above

Workaround

As a workaround for now, before clicking on Save when finishing the comment, uncheck the option "Watch this Page".
