Ability to turn off handleStart's css class additions Declined - Not Valid

In my use of the slider control the "start" (i.e. minimum) position has no special significance over any other position so it's a bit frustrating that the default behaviour of the control is to add a class when the handle is in that position which causes the handle to appear differently  (by adding the e-handle-start class which, in the default material theme, sets the background colour to white and adds a grey border).

Of course I can just add my own CSS for e-handle-start to undo those changes, but it's just a bit frustrating to have to do that!

I can understand that there will be use-cases where the start position is treated as "unset" and so it's useful to have some sort of indicator, but that may not always be the case, so it would be useful to have an enableHandleStart option which would default to true to retain the existing behaviour but which could be set to false to disable the adding of those start-position-related css classes.
