Some time within the last month or so, Confluence's behavior when pasting in a markdown codeblock changed such that any backslash characters are being doubled up (each backslash in the source text results in two backslashes in the resulting codeblock on the page).
We use the codeblock syntax to post command-lines, which is convenient for copy-paste using the 'copy' button. But the 'escaping'(?) of the backslashes negates this utility. As far as I can tell, there is no way to prevent this. No matter what I do, the backslashes are doubled up inside the code block.
For example, if I copy the literal text below on to my clipboard:
```
commandline with a \
```
Then paste it (as plain text) into the current Confluence editor, the resulting code block looks like this:

Like I said, this only started happening recently. In the past this has pasted without issue. Is there any way to disable this behavior?
