A select in grid with thousands of options

[Dennis-N8]

hi,

I have a grid with several select and text input components. One select component has 1200 options.

When I type in an empty new grid with just 2 rows - everything is fast.
When I add 10 records in an empty new grid and type something - it's a bit slow.

Can it be because of many (1200) options?

That's on my developer machine, haven't deployed it to production yet.
