Copy Button not working properly for R

[SvenKlaassen]

Using the Copy Button for the R Code, copies the row numbers, too.

See for example: https://docs.doubleml.org/stable/intro/intro.html

Thanks for reporting this. In an older version, it looked like this:

The line numbers where separated (by a vertical line) and the copy-button did work as intended.
Now it looks like this

and the copy-button is no longer working.

I will check which dependency update did cause this change.

Tried to track it down. From the github actions history it looks like the root cause is in the following diff of package versions

Ok it seems like the combination of Sphinx in version >4.0.0 and jupyter-sphinx somehow causes this problem. The only solution I found so far is removing the line numbers. I think this should be fine. The functioning of the copy-button is definitely more valuable then line numbers....
