Tabulator Midnight theme - row highlighting misbehaves during scroll

[NbrTDB]

Describe the bug
When using the Tabulator Midnight theme, the even-odd row highlighting shifts while scrolling the table (this does not appear to happen on the default Tabulator theme). Shown below are two screenshots taken between scrolls; you can see how the even/odd rows have swapped background colouration.

While scrolling this also makes the table look weird (it looks like somethings wrong/it's not scrolling smoothly as the row colouration appears to "hang" or "wobble" in place instead of scrolling with the text).

It can take a bit of scrolling for the issue to occur; in the JSFiddle I have provided, it begins to happen around the 30th row.

Tabulator Info
Latest version 4.9.3

Working Example

To Reproduce
A step by step guide to recreate the issue in your JS Fiddle or Codepen:

1. Scroll down the table; around the 30th row, the row backgrounds start to oscillate/change while scrolling

Expected behavior
Same behaviour as normal Tabulator theme (i.e. even/odd rows always retain their assigned background colour).

I'm wondering if this is just a CSS issue, really. As a workaround, using the default theme and overriding certain classes to get the same kind of midnight-theme appearance seems to work perfectly well and there are no problems with rows swapping background colour on scroll.

Hey @NbrTDB

This no longer appears to be an issue in the 5.x releases

Cheers
