I've been running into some performance issues with HorizontalPager rebuilding too often (the same happens with a VerticalPager) and decided to debug. Initially, I realized that using `pagerState.pageCount`in a Composable caused repeated rebuilds. I tried to recreate a very simple version of this in a separate project, but surprisingly the issue was not present. I added more and more components from my original project until I was able to recreate the issue <https://github.com/gecko10000/PagerPerformanceMRE/blob/master/app/src/main/java/gecko10000/pagerperformancemre/MainActivity.kt#L30|here>. Running the program and looking at the logs, one can see constant recomposition due to the "Rebuilt" message printing over and over again. Commenting out <https://github.com/gecko10000/PagerPerformanceMRE/blob/master/app/src/main/java/gecko10000/pagerperformancemre/MainActivity.kt#L67|line 67> stops the constant recomposition. I'm not sure I understand why this happens or if this is already documented somewhere, and would appreciate some insight.
