IllegalStateException: Unsupported concurrent change during composition

1. Environment

• OS: [Android 9 (API 28)]
• APP: [ 0.14.1]

2. Describe the bug

Browsing articles (open in reader, return to main list when done, open another). Error message pops up soon after. I might have been moving too fast?

This update fixed some of the big issues I was experiencing, though. Thanks for your work!

Stack trace:

Reproduce the article-reader navigation sequence on Android 9 (API 28) with app 0.14.1, then inspect the stack trace at androidx.compose.runtime.Recomposer.applyAndCheck in Recomposer.kt. Trace the state change occurring during and outside composition; done means the browsing flow no longer throws this IllegalStateException.
