(Unclear whether this is an issue on other wikis; my experience is based on the English Wikipedia).

Feature summary:
On the English Wikipedia, when deleting pages on desktop under speedy deletion, &wpReason= is filled with the reason from the template (example). However, on mobile, &wpReason= is not filled in, which should be done.

Use case(s):

• Go to the speedy deletion category
• Click on one of the pages/candidates
• Open the default deletion interface
• On desktop, the reason for deletion is already filled with the reason used by the nominator. On mobile, the reason is blank.

Benefits:

• Greater convenience for "standard" deletion reasons (no need to use the drop-down menu)
• Greater convenience for non-standard reasons (no need to type it all out again)
