Description

I haven't been able to identify why this occurs, but sometimes users experience a yellow cover over the textField, with a "Strong Password" text on the right, and something cut off on the left. I can still tap the textInput and "Type" but the value does not change within the textInput.

(The red x, and warning text is my own)

I've tried adding, and removing textContentType="password", but this issue still persists.

The report names React Native 0.57.3, iOS 12, Xcode 10, and TextInput with SecureEntry; begin by reproducing the intermittent yellow “Strong Password” state using that environment and inspect the iOS TextInput path. Done means identifying a reproducible trigger and confirming a fix for the unusable field.
