Sub-pixel item heights causing gaps and overlaps between rows

[nikkorn]

Hi, i have been trying to virtualise the row rendering for a table (taking the dynamic height approach) but i have noticed an issue where some rows would have a small pixel gap or overlap by a pixel. I've tracked it down to the defaultMeasureSize function getting the row heights by checking the offsetHeight property of the tr element which gets the value as an integer. Can you think of a workaround for this? I have tried using getComputedStyle(row) in a custom measureSize function and parsing the height property (e.g. "42.23px") but i still get weird gaps and it feels a little hacky. Thanks.
