Steps to reproduce:

1. Open this edited Telerik REPL link, the original link came from TreeView - CheckBoxes, and I only changed "CheckedItems = Data.Skip(1).Take(2)" to "CheckedItems = Data.Skip(1).Take(4)".
2. Run

Expected: Both the parent "Documents" and its 4 children should be checked.

Actual: Only the 4 children are checked; the parent remains unchecked.

This only happens when all children are checked. However, if not all children items are checked, the parent will also be checked.

Steps to reproduce:

1. On Windows 11, go to Settings > Accessibility > Contrast themes and enable one of the themes (e.g., Aquatic or Desert).
2. Try selecting or tabbing through a Blazor Telerik Tree View.

Expected: I should be able to clearly tell what element I'm currently focused on.

Actual: There is no focus indicator.
