Components size is wrongly calcucated

I use Align properties and on some magnifications components size/align is wrongly calcucated. The behavior also depends on the browser used.
I have prepared a simple example of this problem.

What exactly is wrong?
I tested on 3 different browsers and I cannot see a problem:

The problem occurs on my mobile phone (1080x2400) and on some zooms on my computer (1920x1080) - for example 120%, and all below 100%.

Even with different zoom level, I could so far not see this phenomenon here on different browsers.

Maybe on another computer? I tested it on several computers. The problem occurs in about half of the cases. How can I help identify the problem?

There must be something specific in common on the machines where it fails. If you could detect that, that would definitely help!

Alright, I have prepared a test address: https://srv33668.microhost.com.pl/test/test.html
The error can be repeated, for example, here (you can quickly create a free account): https://live.browserstack.com


I tested, among others: Windows 11, Chrome 130.

@brunofierens @TMS_software_team I remind you of the topic- above describes how to reproduce the error.

High workload with recent releases of WEB Core & FNC has prevented us to allocate more time on this so far not reproducible issue. It remains on the todolist.
