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. https://github.com/wix/Detox/issues/921

What was the expected behaviour?

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

Was it tested on latest Detox?

• [X] 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?

Detox version: 19.9.0 React Native version: 0.66.4 Node version: 16.14.0 Device model: iPhone 13 iOS version: 15.2 Test-runner (select one): jest-circus

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