Describe the bug
Whenever I use :emphasize-lines: within a .. code-block::, the newline in between the line(s) that is emphasized and the next disappears after copy-paste via sphinx-copybutton 0.5.1. There is no such problem with 0.5.0.
Reproduce the bug
The below simple example shows the bug:
.. code-block::
:emphasize-lines: 1
a = 1
b = 2
The Sphinx generated HTML renders as
a = 1
b = 2
Copying using the copy button and then pasting should preserve this, which is indeed the usual behaviour (e.g. sphinx-copybutton 0.5.0). With sphinx-copybutton 0.5.1 however, pasting results in
a = 1b = 2
