Bug 240065 – REGRESSION(r293038):[ iOS ] fast/forms/auto-fill-button/input-auto-fill-button.html is a consistent failure

• Status: RESOLVED
• Resolution: FIXED
• Component: New Bugs

[Karl Rackler]

Description:
fast/forms/auto-fill-button/input-auto-fill-button.html

The first failure that I saw on the dashboard was 4/19/2022 at r293040.  r293038 updates in-field icons for credential fields so that probably introduced the consistent failure.
