For our dev tickets, it is common to have curly-code-curly ({code}) blocks with snippets of scripts and source code. IMHO, wrapped text is a disaster for code and script snippets.
Now, I could swear that Jira (server/datacenter) "always" rendered them with a horizontal scroll bar, so that long command line or script examples could be copied out of the issue view and directly pasted without having to clean up extraneous line breaks inserted by the browser rendering of the issue comments.
With our current version v9.12.18#9120018-sha1:85931da of Jira Datacenter however, "{code}" block DO NOT have horizontal scrollbars (anymore??) but the lines are rendered wrapped.
The "{noformat}" markup has horizontal scroll bars -- but I basically first heard about this when researching this situation.
Now, I found some old tickets and posts, and from the tickets I found:
it seems there has been a period (see esp. JRASERVER-34877 ) where Code Blocks where rendered WITH horizontal scroll bars (Jira 5) and then with Jira 6 wrapping was introduced for Code Blocks (h-scroll only kept for noformat).
However, Jira 5 is way too old for me to remember horizontal scroll bars from that one.
So, either they have been changed, there have been variations (maybe Server/Datacenter vs. cloud?) or I'm just imagining ever seeing h-scroll for {code} blocks??
If anybody has a succinct "history of h-scroll for preformatted text in Jira" I would be really grateful.
