Both single click and double click should not enter edit mode. You can select text by single-clicking prior to the first character you want to select and then shift-clicking after the last character you want to select. Removing click-to-edit completely would fix this use case.
Additionally, making the description a “safe to click” area would help with editing other fields. When done editing a field, you need to click out of it in order for it to save before closing the page/tab. Currently, the Jira issue page has very few small areas of safe-to-click whitespace. If the Description field became a “safe to click” area, this would speed up editing other click-to-edit fields.
