Please keep current value when releasing SHIFT while sliding in textbox!! (prevent jumps)

When sliding a value in a textbox and than holding SHIFT for smaller increments/finetuning, the value makes a huge jump when releasing the SHIFT key.

Instead of keeping its value, as we might expect, it's now recalculating the value from the moment we started sliding, but now ignoring that we ever used the SHIFT key to have smaller increments. That's not right IMO.

So basically after releasing SHIFT we now need to start all over again to get to our value, which doesn't make much sense.

So please keep the current sliding-value when releasing the SHIFT key while in 'sliding-mode'!
