[Ray Serve] Copy and paste code snippet also copies line numbers

[robertnishihara]

Description

On this page https://docs.ray.io/en/latest/serve/model_composition.html

When I click the "copy" button in the upper right corner of the code snippet, it copies all of the line numbers (which prevents the example from working).

This is what it looks like after pasting the code into an editor (the line numbers should not be pasted).

This is probably a problem in multiple places in our documentation, not just here.

This is a known problem. The workaround is to turn off line numbers, but in these cases the line numbers are needed to refer to specific lines of code in the docs. This is a docs infrastructure/tooling issue. @peytondmurray, do you have any ideas on how to fix this?

I was never able to reproduce this issue on my local machines, and I expect it to depend on what browser and what version you're using. There are CSS styles which control the selectability of elements, but they're browser-dependent. Even forcibly overriding the styles of the <span> elements that contain the numbers didn't seem to work for @angelinalg. Being unable to replicate the problem I'm unsure exactly what the best way to proceed with this issue would be. See https://github.com/ray-project/ray/issues/39652 for more information.

I can spend a little time digging into sphinx_copybutton to see if there's something there I can change. For now, I'd propose closing this issue as a duplicate of #39652.

This issue is slightly different from #39652, which is doing a copy and paste. @MattEWeber is able to reproduce this one, which uses the "copy" button, but not #39652. I suggest we keep both open as they seem to be different mechanisms.
