12.0p BatchUploader preview ListGrid leaves edit mode on fast tabbing

[Blama]

Hi Isomorphic,

I just noticed a behavior in our app, that also happens in the showcase (v12.0p_2020-01-22).

If you upload the demo file, double click the 1st cell and tab fast / keep tab key pressed, the ListGrid will leave edit mode, which is unexpected.
This does not happen in normal ListGrids, e.g. here or here with canEdit: true.

This is minor for me.

Best regards

Hi Blama
A couple of quick clarifications:
1) Do you mean that it reaches the end of the grid and then leaves edit mode, or that it jumps out in the middle of one of the earlier rows?
2) Which browser are you seeing this on?

Thanks

Hi Isomorphic,

I meant "jumps out in the middle of one of the earlier rows".
Please see this video (v12.0p_2020-02-13), where I tab slowly in the 1st two rows (OK) and fast in the other ones (by keeping the "Tab"-key pressed), where it breaks.
Tested in Chromium 80.0.3987.87
