This isn't really a duplicate.

What is the difference? :)

This is a bug really. We don't close the dropdown when leaving the editing state. Another issue is a feature request on when exactly to leave the editing state.

Got it, thanks for clarifying!

Hide "edit generated password" prompt when leaving the editing state.

It's questionable whether the popup should move back to the generation state.
Curently for automatic generation it does and the bug isn't observed. For
manual generation it doesn't and therefore the editing prompt remains open.
The CL fixes that.

Add tests for deleting the generated password.

This is a follow-up to https://chromium-review.googlesource.com/c/chromium/src/+/1160849.
The tests are not to be merged back to M69.

I'd like to merge r580516 back. It's a bug fix for the password generation scheduled for M69.

This bug requires manual review: M69 has already been promoted to the beta branch, so this requires manual review

Is the change well baked/verified in canary, having enough automation tests coverage and safe to merge?

The change originally landed in 70.0.3512.0. Now it's 70.0.3515.0. I added an interactive UI test for it. The change is safe and tiny. It doesn't affect anything beyond password generation.

Approving merge for r580516 to M69 branch 3497 based on comment #10 and #13. Please merge ASAP so we can pick it up for this week Beta release. Thank you.
