18911	"Clicking on layer's opacity slider ""toggles"" instead of sliding"	blackboxlogic@…	team	"==== What steps will reproduce the problem?
1. Have JOSM open with a layer.
2. In the 'layers' pane, click the button labeled ""change visibility of the selected layer""
3. In the popup, notice that there is an opacity slider, currently at 100%
4. Click in the middle of the slider to select a value near 50%

==== What is the expected result?
I expect the slider to slide to the position/value clicked by the user

==== What happens instead?
The slider acts more like a toggle, jumping in the direction of the click to the extreme value in that direction.

==== Please provide any additional information below. Attach a screenshot if possible.
This slider behaved as expected previously. I do not know when the behavior changed. Recently I have updated JOSM to latest and updated my JAVA version.
