Description

I have requirement that when Editor have long text and it is not being edited, I want to show only 2 or 3 lines with ellipsis and when that field is being edited the full text should be visible.

For this I have created custom Editor control, source code is attached in repository link section. I have noticed few bugs in Editor which is as mentioned below:

1. In iOS the Cursor is not getting set to the last position when getting focus in Android it works just fine.
   • It getting set in between anywhere in the editor.
   • It sometimes selects the word when focused.
2. OnMeasure method is also not getting called in iOS, this again works fine in Android.
3. Unfocused event is not working if tapped outside of editor control for both Android & iOS.
   • When there is not other input control is available on page
4. In iOS when Editor gets control it scroll downs the entire ui from top and restored it back once the keyboard is hide.

Steps to Reproduce

1. Open demo project and run in iOS simulator or device
2. Start typing longer text till in first Editor it shows 4-5 lines
3. Moved to second editor and notice that first Editor just shows 2-3 lines with ellipsis
4. Now if you go to first editor again, it will show full text but the cursor is getting set in between of text or select word (in iOS only
5. Add the debug point to OnMeasure in iOS its not getting hit, for Android it does get called.
6. Do the same process in Android and see it will work fine
