Is your feature request related to a problem? Please describe.
It's more of a nitpick. When copying the style for example of a line, which has line caps and join set to 'round', these properties are not applied when pasting to the new line. It's rather annoying when trying to keep up with a certain style.

Describe the solution you'd like
I don't know how styles are copied and pasted, so I'm not sure how this is to be solved. If the copy paste functionality uses something like a table or list of properties, then I'd guess adding the mentioned properties to the list would (maybe) fix that?

Describe alternatives you've considered
CTRL+A and then configuring the properties, but this seems like a duct taped solution.
