ComboBox jumps in ScrollViewer in browser

[yll690]

Describe the bug

If I put a ComboBox in a ScrollViewer, and click the ComboBox after it selected a value, the ComboBox will jump up and down. On windows there is no such problem.

To Reproduce

Create a new multi-platform project that includes browser(and desktop) and input something like this, run the browser project and click the ComboBox. You should see same behavior like the gif.
