I agree with John that a layout algorithm that uses incremental calculations 
will always be flawed in principle. The correct approach is to store the 
initial configuration, and then for each configuration change, go back to the 
initial configuration and recompute the layout solution.

Now, we might still accept a bugfix for a flawed algorithm. But JDK-8299753 is 
an enhancement, not a bugfix. I'm not sure what to make of this: it's obviously 
a flawed approach, and basing an enhancement on a flawed approach means that 
someone would have to come back to this issue in the future and solve it 
correctly.

I don't think that the issue at hand is so severe that it's a forced move to 
integrate this interim solution.
