I'm running on Confluence DC 7.19.3 and published a page with a code block using the code block macro. While in a published state, I am unable to select text in the code block to copy and paste (ie to a terminal). The block essentially appears to be an image that doesn't allow selecting of any text. My workaround is to edit the page and select the code, but that kind of defeats the purpose.
I know this is possible as another instance for which I do not administer, can perform this functionality. Is there a configuration setting to change this behavior?
