TextInput.Password Mode Shows Clear Text

I created a new QML project with only a TextField component and set the echoMode to TextInput.Password

I noticed if you start entering text with a letter, both letters and numbers are displayed in the clear. If you start with a number, it will display hidden as long as numbers are entered, and will become clear as soon as you enter a letter, so this toggling effect is noticed when switching between entering numbers and letters. According to logging, the onTextChanged event doesn’t trigger for letters.

This seems to be linked to QTBUG-127541.
