It is currently not possible to double click the number input on Feed Mill to select its contents, nor use mouse cursor to position the caret.
[Some technical reverse engineering stuff, sorry, I couldn't help my curiosity]
This appears to be caused by the select and input being inside an anchor tag which causes Framework7's `handleClicks()` to prevent all default events. Interestingly I didn't see this anchor structure appearing anywhere else (except in one place commented out)
