replaceText duplicates the string when a maxLength is set

[kaibarnes]

What happened?

In a TextInput with a maxLength prop set, calling replaceText with a string that has a length over half of the maxLength causes the string to be repeated at the start of the input.

For example

<TextInput testID='testInput' maxLength={10} >

element(by.id('testInput')).replaceText('abcdef');

causes the TextInput value to become abcdabcdef

It seems this was reported back in 2018 but wasn't addressed. #921

What was the expected behaviour?

That replaceText would only enter the specified string once in the TextInput

Was it tested on latest Detox?

• I have tested this issue on the latest Detox release and it still reproduces.

Did your test throw out a timeout?

• I have followed the instructions under Identifying which synchronization mechanism causes us to wait too much.

Help us reproduce this issue!

1. Create a TextInput component with a maxLength, e.g. maxLength={10}
2. In a test, call replaceText on the above TextInput using a string with a length >= half of the maxLength, e.g. 'abcdef'
3. Run the test and see the TextInput value become abcdabcdef

In what environment did this happen?

React Native version: 0.66.4
Node version: 16.14.0

It seems this issue is still reproducible on 20.17.0.
Except using typeText instead, any other way to fix it?

@lclnrd Hopefully, Asaf will be back soon (we miss him too) and will be able to look. Otherwise, pull requests are welcome.

Issue still persists on v20.25.1. Any updates on this would be hugely appreciated
