I see. Indeed, I didn't see any significant difference among branches.

I observe the first-loading time is very long...

Can you tell me more about this? I'll try to reproduce and measure the performance.

I tried to measure the performance 
by running all the cells as shown in the image

but I could not find any significant difference.

However, I'm not very confident if this actually measures the css performance.

@SimonHeybrock, do you have any suggestions how to measure the peformance?

What I did in this experiment is to make a notebook with hundreds of empty cells with xarray under these branches.
Refreshed the browser to render the htmls.
Number of cells are the same in all these experiments, but only the xarray branches (and produced html) are different.

Maybe we may need more cells?
Any advice would be appreciated.

looks working with a darkmode, but I'm not sure if this solves the original problem.

It looks to me that defining custom properties in `html[theme=dark]` may cause the same problem.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,863506023

> @fujiisoup added the vscode dark mode support, maybe he has ideas.

I did it in #4036 but this was actually a workaround and should be improved by an expert.
I'll take a look, but with little hope to fix.
