Using Chrome under Android (on a Samsung Galaxy S5 running Android 5.1), when setting focus on the MaskedTextBox, when I start typing on it the first value is ignored and the second value is added to the input field. If I try to edit the value I entered, the cursor jumps to the right side of the object and sometimes can't delete values and seems to get stuck.
Using Safari under iOS on an iPhone, everything seems to work properly except when focusing outside of the MaskedTextBox and giving it focus again, it pads the value entered with empty spaces.
I isolated the code below. Am I doing something wrong or is this an issue with the MaskedTextBox control under mobile browsers?
I'm using UI for ASP.NET AJAX Q2 2016 for the 4.5 .NET Framework.
