Lines partially missing after upgrade from 4.3.0 to 4.3.1

[StephanTLavavej]

Expected behavior

I don't yet have a fully reduced, interactive example - my apologies (as someone who has to deal with toolset bug reports all day too). Please close this issue if you absolutely require one, and I'll see if I can extract it. I'm hoping that there are few enough changes between 4.3.0 and 4.3.1 that this rings a bell.

I have large chart with several years worth of weekly followed by daily data points (so >1400 per line). With chart.js 4.3.0 it renders perfectly, as seen in https://microsoft.github.io/STL/ with source code https://github.com/microsoft/STL/tree/gh-pages .

Current behavior

With chart.js 4.3.1, it mostly renders, but the older portions of lines are missing. Side-by-side screenshots:

https://stephantlavavej.github.io/STL/ is using chart.js 4.3.1 with source code https://github.com/StephanTLavavej/STL/tree/gh-pages .

Curiously, chart.js knows about the data points that aren't being displayed on the lines, as the hover tooltips indicate that their values are there.

I took these screenshots with Edge, but it repros in Chrome too.

I have fully reduced this and will open a fresh bug.
