Thicker border in 3.5.0+

[muss0v]

Expected Behavior

Same as version 3.4.1.

Current Behavior

Since version 3.5.0 the border thickness has increased for the chart (but not legend).

Possible Solution

Decreasing the "borderWidth", but that also affects the border used in the legend which I don't want to change.

Steps to Reproduce

You can check this behaviour in the documentation (compare latest version vs 3.4.1.):
https://www.chartjs.org/docs/latest/samples/bar/border-radius.html (thicker border)
vs
https://www.chartjs.org/docs/3.4.1/samples/bar/border-radius.html (OK border)

https://www.chartjs.org/docs/latest/samples/bar/horizontal.html (thicker border)
vs
https://www.chartjs.org/docs/3.4.1/samples/bar/horizontal.html (OK border)

Might have to resize your screen for a better comparison (in the latest version the chart is much larger in the documentation).

Context

Since version 3.5.0 (also in 3.5.1) the border thickness has changed. It's more bolder now.

I always used "borderWidth: 2" which was perfect for my case, but now it's too thick. When I use "borderWidth: 1" it's thinner than before and also the legend border changes (which I don't want).

The only border related change I saw in 3.5.0 was #9452 which does not appear related.

@kurkle any ideas? Could this be a pixel alignment issue?

I suspect this comes from #9399
