Textbox Focus

When making stock adjustments, when in "non-zero Stock", I click on '+ Add more Items ' and as you will see in example 1, the text box is ready for me to make an entry.  It's focused.

When making stock adjustments, when in "Zero Stock", I click on '+ Add more Items ' and as you will see in example 2, the text box is not ready for me to make an entry.  It's not focused.
I have to click 'type to search...'.

It's inconvenient to have to do this each time. and has meant a lot of typing, and then realizing that the textbox is not focused so I have to click it and start typing all over again.

I would be really grateful if you could make an update and have that textbox focused ready for typing.
