Unexpected behavior when using Copy button along with showLines parameter

[malberts]

Use this wikitext:

{{#embed:https://github.com/ProfessionalWiki/ExternalContent|lang=md|lineNumbers|showLines=1-3,5}}

Then click the Copy button. The copied text is the full file, but with broken whitespace:

---

The copy button behavior should do one of the following:

1. copy the visible lines
2. copy the original full file correctly

Most likely (1) is more the expected behavior.

Yes, should only copy visible lines. Though copying the entire file is already better than copying a messed up version of the entire file.
