[pve-devel] [PATCH proxmox-widget-toolkit 1/3] fix #5588: notification: smtp: fix 'Authenticate' checkbox in Chromium

[Michael Köppl]

Tested this on the latest master with both Chromium 137.0.7151.68 and
Firefox 139.0.1. Was able to reproduce the original issue #5588 on PBS
in Chromium before applying the patches.

Ensured that:
- the "Authenticate" checkbox stays unchecked in Chromium
- "Unchanged" is only shown as the empty text *with* authentication
activated
- the password field is actually empty upon creation of a new SMTP
target, instead of showing "Unchanged"

Did not notice anything off. The implementation looks good to me. I
spent a few minutes tinkering around with an alternative approach of
detecting whether the user had previously entered a password, but the
approach in 2/3 is works as expected and doesn't add unnecessary complexity.

Consider this:
