I've actually found that the bug is a little deeper. If you start at 10,100,1000 etc and drag it to lower than half of it's value you are limited to half of the value you started at. This seems to happen specifically at 10/2, 100/2, 1000/2, 10000/2.

Steps: Start at 10 drag to less than 5, unable to drag higher.

Yes it is intentional. The value is clamped to a range that is what is most believable for a photo-realistic render.

@Lariatch (Lariatch) What you describe in your comment is normal behavior if you enter the value manually above the soft max value.

Edit : Also we kept the range as [0 .. 0.1] because it is an "alpha" value and thus 1.0 is the full effect opacity (which is way too strong).
