It can, but this is likely a bug if it happens.

I'm advocating for x-www-browser to exist, but haven't done the work
to make it so. Note that the authorative list of virtual package names
in policy is out of date. (I have some other ideas about fixing that
which I want to pick up too)

www-browser is an alternative, provided by (at least) lynx.

Yes, but that is effectively doing the work of defining a virtual
package but in the LXDE dependencies. We might as well do it properly and
in the right place from the start.

Personally I agree that this should be a Depends:. I'm not sure the LXDE
maintainers agree. I think Recommends: would be acceptable *if* LXDE's
behaviour was to not show the button/shortcut if the path it was
pointing at was non-existent (perhaps this is achieved via TryExec=).
But that's not the current behaviour.
