**Problem description:**
Sometimes when switching between tabs in `TabControl` old tab content is rendered on top of new tab.

App has multiple tabs. One of which has `HostHwnd` that starts another wpf app process with `DataGrid` (Grid content has high refresh rate). Sometimes when switching between tabs, recently updated content from HostHwnd is rendered along site newly selected tab.

Tabs do not have to be changing so quickly like on videos above for that glitch to appear. Its was just for video purpose done like that. It does not happens often but users reported its usually when switching to new/empty tab when there are a lot of updates processed by DataGrid

**Actual behavior:**
Sometimes old tab content is displayed in place where content from new tab should be

**Expected behavior:**
Always correct content is shown

**Minimal repro:**
