TreeViewSwappingNodesTest_ContentMode fails on WASM

[MartinZikmund]

Current behavior

TreeViewSwappingNodesTest_ContentMode UI Test fails on WASM as the fourth TreeView fails to materialize its items. This is possibly due to some data binding issue. The test is currently ignored.

Expected behavior

Test should pass. Test should be un-ignored.

How to reproduce it (as minimally and precisely as possible)

Un-ignore the TreeViewSwappingNodesTest_ContentMode UI Test and run it on WASM.
