[BUG]: Inital page size not working when using a dynamic PageSize

[PowerThomas]

Describe the bug
Using the Details List component in an MDA Custom Page. I have a global variable in the App.OnStart where I set the PagingLimit value from the User Settings table of the current user. This variable is bound to the PageSize property inside the DetailsList component. When refreshing the page in the browser, the page size is more than the actual page limit set by the user. When using the pagina navigation, the page size is correct.

To Reproduce
Steps to reproduce the behavior:

1. Set a global variable representing the page size
2. Bound this variable to the PageSize property
3. Publish
4. Reload the page

Expected behavior
PageSize should match on initial load.

@PowerThomas on the first page when the scroll bar is shown, are you able to scroll down and view more records than the page size allows, or is the scroll bar just rendering incorrectly?
