Going back from MessagesScreen sometimes doesn't work

Describe the bug
Going back from MessagesScreen sometimes doesn't work.
onBackPressed callback of the MessagesScreen composable is not invoked. This happens if you enter the screen while keyboard is opened or is closed at the time of navigating to MessagesScreen. Cannot go back even when you close the keyboard/send a message/reopen and close keyboard.
In MessagesScreen, there is a line to check if keyboard is opened:
val isImeVisible = WindowInsets.ime.getBottom(LocalDensity.current) > 0

However in the case above this value always seems to be true when using it in the back handler.
It seems it doesn't take this value into consideration so it seems like it uses the first value, and never updates.

val isImeVisible = WindowInsets.ime.getBottom(LocalDensity.current) > 0
val backAction: BackAction = remember(listViewModel, composerViewModel, attachmentsPickerViewModel) {
        {
            val isStartedForThread = listViewModel.isStartedForThread
            val isInThread = listViewModel.isInThread
            val isShowingOverlay = listViewModel.isShowingOverlay

            when {
                isImeVisible -> Unit
                attachmentsPickerViewModel.isShowingAttachments -> attachmentsPickerViewModel.changeAttachmentState(
                    false,
                )

                isShowingOverlay -> listViewModel.selectMessage(null)
                isStartedForThread -> onBackPressed()
                isInThread -> {
                    listViewModel.leaveThread()
                    composerViewModel.leaveThread()
                }

                else -> onBackPressed()
            }
        }
    }

If we add isImeVisible to remember's keys, then it seems to be working fine:

val isImeVisible = WindowInsets.ime.getBottom(LocalDensity.current) > 0
val backAction: BackAction = remember(listViewModel, composerViewModel, attachmentsPickerViewModel, isImeVisible) {
        {
        ....

To Reproduce
Steps to reproduce the behavior:

1. Let's assume that you have some screen where you can search your channels
2. Search for a channel(let the keyboard be open)
3. Go to Messages screen for that channel
4. Trigger system back press or toolbar back button
5. Nothing happens

Expected behavior
User is able to do whatever their onBackPressed callback is supposed to do, e.g. navigate back.
However, onBackPressed callback is not invoked.
