[Bridgeless] Multiple bundles loaded on android when locale changed natively

[itsramiel]

Description

I am developing an android module that changes the app locale using AppCompatDelegate api setApplicationLocales as in the android guide which reloads the app as a side effect, but every time the locale is changed and I refresh the app an extra line of:
Running "SampleApp" with {"rootTag":101,"initialProps":{},"fabric":true}
is logged to the console. I am not sure if this means there are multiple bundles loaded and there is a memory leak?

I added a console.log to App.tsx and that console.log is only logged once not as many times as there are the Running .... lines so I am not sure about the multiple bundles loaded term

Check videos below to better understand

Happens only on bridgeless

Steps to reproduce

1. clone the reproduction repo
2. install dependencies with yarn install
3. run android app with npx react-native@latest run-android
4. click on set locale button
5. refresh the app <<----- You should see an extra Running "SampleApp" with {"rootTag":101,"initialProps":{},"fabric":true}

You will see the Running.... as many times as you pressed on the set locale.

Note that the set locale button simply changes the app language as recommended by android and also that it works when bridgeless is disabled

@itsramiel thanks for attaching a reproducer here.
This is indeed an interesting bug and there is something going on with Bridgeless. I'll try to look into it and get back to you

@itsramiel Thanks for reporting. I did confirm this was a problem but it was recently fixed here: PR #44873
@cortinico The change log for the PR probably needs to be updated to state what was fixed.

Awesome I will be closing this, and recreate the issue if it still exists after the pr. Do you know which version will have the changes in the pr?

In theory this should go out in 0.76. If you want it to be picked in 0.74/0.75 you should open a pick request here:
