[Problem/Bug]: The password save prompt does not appear

What happened?

There is a Windows Forms application with a login feature implemented using WebView2 (introduced in September 2024). Until mid-January 2025, password saving was being suggested after logging in, but since around January 22, the suggestion to save the password suddenly stopped appearing. (This happens across all environments with Windows 10 and 11.) During this period, no changes were made to the Windows application, login form HTML, or JS.

Upon investigation, I found that when I reverted the WebView2 Runtime version from "132.0.2957.127" to "131.0.2903.146" via Group Policy, the password saving suggestion reappeared. Based on these results, I suspect that the issue is not on the application side but rather with the latest WebView2 Runtime version.

Do you think the reason for the disappearance of the password saving suggestion is a bug in the Runtime, or is it due to a change in specifications? (I checked the release notes, but I couldn't find any information related to password saving.)

If it is a specification change that requires application-side adjustments, immediate action is necessary. I apologize for the inconvenience, but could you please investigate this urgently?
