copy button is not displayed for longer code block

[zclab]

I found that there is no copy button for longer code block which is 40 lines or more.

Expected behaviour

Actual behaviour

I use: Python 3.8.9, sphinx 4.4.0 and sphinx_material 0.4.0

It looks like the doc-string's indentation is different by a level. I doubt that would fix this though. What was the last version number with the button that had worked for you?

[zclab]

It worked on sphinx_material 0.3.1

I noticed that this happens with the auto-docs' generated source code pages

Still looking into this...

Well, this isn't a problem in mkdocs-material, but it definitely is something we merged in from upstream v8.2.5 - I suspect it is something to do with the changes made to mounting code blocks for large pages (a speed up to satisfy squidfunk/mkdocs-material#3643).

TL;DR - Still not exactly sure what we merged from upstream that is causing this issue. I'm focusing on this file's diff.

This is actually an upstream bug that was fixed here:
squidfunk/mkdocs-material@88cfda4

We just need to merge in the updates.

Note: The best way to check if something is an upstream bug is to reproduce using the version of mkdocs-material listed in MKDOCS_MATERIAL_MERGE_BASE.

yeah, that was my bad. Even more motivation to resolve the merge problems with recently v8.2.8+.
