Maximum call stack size exceeded at 90% zoom

[m3ftwz]

Describe the bug
Under certain circumstances, Tabulator throws a call stack size error when browser is zoomed out at 90%.

Tabulator Info
Tabulator version: 6.3.1

Working Example
https://jsfiddle.net/w0zporka/

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

1. Go to https://jsfiddle.net/w0zporka/
2. Click on 'Run'
3. Zoom out the browser page to 90%
4. See error on console

Expected behavior
I would expect a redraw without errors

Desktop (please complete the following information):

• OS: macOS 26 and Windows 11

• Browser: Chrome

• Version: 140.0.7339.214

Additional context
This issue might be linked to #2974 which has a very very similar error.
Another point is that the JSFiddle was run on different machines by different users, and while some encounter the error, others do not. I haven’t been able to narrow down the cause further to provide more details.

Today I discovered, that some tables in my system are hitting this issue. I have no idea, why some of the tables are hitting this, and some not. They are using the same configuration, they differ only in columns (number of columns, labels, data)... All tables are showing only a dozens of rows. I do not remember this with previous version, or previous Chrome version (currently on 140.0.7339.214 on macOS), but these tables are not accessed every day... I tried to set the renderVertical to basic and this helped with ONE table, but not all. It's even more weird, because it does not happen, when the table is too wide to fit on the screen. When I shrink the browser, this bug does not come up. When I widen the browser to fit the table, it loops and falls into stack overflow.

Had this same issue....changed layout from "fitColumns" to "fitData" and it's faster and cannot reproduce the infinite loop. Can reproduce easily with "fitColumns" and zoom set to anything but 100%.
