> However, I have one question, html text is honouring "font-size" value(say 1.5 as per testcase) but if Display resolution in windows system setting or via -Dsun.java2d.uiScale is set to something different(say 1.25), then should it honour the font-size property (1.5) or Display resolution (1.25)?

Shouldn't UI scaling be applied automatically? The font size in user space should remain the same, yet the actual font size would be scaled up according to the DPI setting. That is in my understanding, CSS rule applies 150% to the base font size according to its rules; then `uiScale` is applied to whatever the computed font size is.

Does it make sense to run the test with different `uiScale` explicitly?
I ran the test on my laptop with 150% scaling, it passed successfully.
