Description
What happened?
With CoreWebView2.Profile.IsPasswordAutosaveEnabled = true, submitting a login form with a new credential no longer shows the Save Password prompt on Evergreen runtime 152.0.4191.x.
Autofill of credentials that were saved earlier (under 151) still works on 152, so the password store is readable and the setting is honored for fill. Only the save/prompt path is affected.
Pinning the same app, same SDK, same page to Fixed Version 151.[x.x.x] via CoreWebView2Environment.CreateAsync(browserExecutableFolder: ...) restores the prompt. No other changes between the two runs.
Steps to reproduce
await webView.EnsureCoreWebView2Async(env);- In
CoreWebView2InitializationCompleted:
webView.CoreWebView2.Profile.IsPasswordAutosaveEnabled = true;
- Navigate to the attached minimal login page (username field +
type="password"field). - Enter a credential not previously saved for this origin, submit.
Expected
Save Password bubble appears (as on 151).
Actual on 152
No prompt. Nothing is written to the profile's password store.
Additional observations
- Credentials saved on 151 autofill on 152: yes
- Same page in the Edge 152 browser: [prompts]
Importance
Important. My app's user experience is significantly compromised.
