When I've implemented first the inline autocomplete feature (4.1.0) I chose to store the autocomplete data source path in a data attribute (data-issue-url) of each textarea field that support this feature. The solution touched 9 views files (r18444).

Since then, new requests came to support inline autocomplete for other sources like macros or wiki pages (#33425, #33820) and if we keep the current solution, we need to touch again the same files and add two new attributes. On a long term, the solution doesn't seem very efficient.

My proposal is to change the current implement and store all the paths in a JS variable, attached an working version.

Any feedback on this is really appreciated.
