Proposal list not closing on blur

[topkat]

Hi, I use tab to switch input focus and noticed that sometimes two proposalList are open and mess with my previous selected value for another input. My keyboard selection goes to the previous wrong input.

I have seen that you commented near line 125 the proposalList.empty(); that occur onBlur...

The solution could be just to uncomment that line
OR to empyty proposal list on tab key

I'm ready to make the change when I know the good solution.

Thanks for such a well written and simple library :)
