Supports floating in mid air

[nomike]

Description of the bug

I sliced an object and the generates supports are floating in mid air.
Although the original author of the design claims that supports are not necessary for this particular print, I still believe supports should not be generated in mid air.

If they do, which in this case seems to be because of the bump in the straw (a sign that snug supports might be the wrong choice here), at least a warning should be presented to the user.
