Todo example does not work when coroutines are added to the main module

[arkivanov]

STR:

• add coroutines to the main module: implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.4.1")
• run desktop app

Actual: the window is blank Expected: a working app

I see that all Composable functions are triggered with valid data but nothing is rendered. Looks like the Crossfade function becomes broken. Removing Crossfade fixes the issue:

I noticed on my app adding coroutines makes TextFields very buggy and very few keystrokes are recognised

FYI org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.9 works OK with TextFields, but org.jetbrains.kotlinx:kotlinx-coroutines-core:1.4.0-M1 or higher does not.

Fixed in 0.2.0-build128. I checked that todoapp works if we add coroutines 1.4.1 in main module.

Was fixed in: https://android-review.googlesource.com/c/platform/frameworks/support/+/1495139
