Gallery lose tab seqence after field value changed.

[NewBee117]

Hi, I have a gallery with 3 input fields, tab index 11, 12 and 13. Without changing any fields, tabbing through the fields and to the next line without any problem. However, if I update the value on any field, tab out of that field will bring the tab focus outside of the gallery, instead of going to the next field or row. Any idea how to fix this? Thanks.
