TAB key is not moving the focus on first click after the date is deleted in IE11

[dafo]

Description

After deleting the entire date, and pressing the tab key (in order to go onto the next field), it won't go on the next field but select the date editor's mask, so the user has to do it a second time (it's not the case in chrome, Edge and FF). This is not the case for the igMaskEditor

Steps to reproduce

1. Run the attached sample
2. Focus the date editor and delete the value
3. Press Tab key

Result

The mask is selected See the attached gif

Expected result

The focus is moved to the next field
