Steps to replicate the issue (include links if applicable):

• On Wikimedia Commons, go to Preferences > Editing and turn on the "Enable section editing by right clicking on section titles" option (is this newly added and/or enabled by default? I don't recall enabling it): [ https://commons.wikimedia.org/wiki/Special:Preferences ]
• On mobile, long press the title of any pictures (eg, press and hold "File:WiktionaryEn - DP Derivative.svg" on the page [ https://commons.wikimedia.org/wiki/File:WiktionaryEn_-_DP_Derivative.svg ])

What happens?:
The editor is pulled up for the lede (which I think is empty on all Wikimedia Commons pages)

What should have happened instead?:
The selected text should be highlighted, allowing you to copy it, etc. This is the functionality on other wikis like Wikipedia and Wiktionary: enabling the setting allows you to long-press subheadings to edit them on mobile, but long-pressing the article title simply highlights the text. This is intuitive because selecting/highlighting the name of an article is extremely useful.

Admittedly though, the name of the option is a bit misleading, and I would not have expected it to apply to mobile editing at all given that it says "right click", and personally I think there should be a separate option ("edit by long press on section titles") for the mobile equivalent. It was only by trying to figure out why this was happening that I stumbled upon the setting at all and tried it out.
