As per forum thread https://www.telerik.com/forums/autocompleteview-causes-memory-leaks ACV control causes memory leaks on iOS.
Here is the repro project https://github.com/VitalyKnyazev/AutoCompleteViewLeak
Setting the FontSize property of the AutoCompleteView control to anything larger than 20 badly clips the text of both watermark and selected/written text, at least on iOS. I've tried various "hacks" with increased control heights and/or padding, themes etc, but it doesn't matter, it still clips.
Seems to work fine using RadEntry for example, so it should really be the same with AutoComplete?
Reproducing is as obvious as setting the FontSize property.
