Fragment's menu not localized on rotation

[RumataEstorish]

Steps to reproduce:

• Create fragment
• Add menu to fragment
• Rotate device

If you add something like this:
override fun onPrepareOptionsMenu(menu: Menu) {
super.onPrepareOptionsMenu(menu)
menu.clear()
MenuInflater(activity?.applicationContext).let {
it.inflate(R.menu.main_menu, menu)
super.onPrepareOptionsMenu(menu)
}
}

it solves problem, but adds new one - app:showAsAction="always" is ignored

I've created fork to test this out and maybe add some fixes if have any, but no luck.

Unfortunately, I can't reproduce it across different android versions on emulator and my Pixel2 using your sample project.
What device are you testing on?

Ok, lets add more steps to reproduce :)

Environment:

• Emulator API 28 (Pixel 2 XL skin my case)
• Languages: English primary, Russian secondary
• Auto rotation is turned ON
• Device orientation - portrait

Steps:

• Open app. Language is English
• Switch to Russian
• Press "Screen 1"
• Open 3 dots menu. Observe "второй пункт меню". Note first menu item displays as icon for test needs (yes, green on green bar :))
• Without closing menu rotate emulator.

Expected result:

• We still see "второй пункт меню"

Actual result:

• We can see "second menu item"

Note:
Fragment stays in Russian as expected and we can see "произовольный текст 1"

Okay, just reproduced it. It's important to keep the menu open before rotating the device to replicate the issue.

Will dive deeper and see what I can do. Thank you for reporting!

Well, there are more cases when this can happen. Not only when menu is kept opened, but when you open/close navigation drawer and some other. But they require much more code for testing.

Unfortunately, only option I've used to solve this is manually set title for each menu item in onPrepareOptionsMenu.
