Z-index for floating components is computed in a wrong way.
It starts at 1800 and for every other floating component increases by 1.

That's a bit wierd.
It has bad results when you need to have some floating block, for example bar with some input fields and non floating block with some input fields.

When i use position: absolute; z-index: 1900 on the floating bar, all of the notifications are bellow bar.
When i don't use position: absolute, all notifications are above floating bar.
What i need is, that all notifications are bellow the floating bar except notification on element inside the floating bar.

I would expect that z-index computation depends on the reference component context, thus value of z-index is only a bit higher then the highest z-index of the context.
So notification for component which is inside block with max. z-index = 500 should be above the block and notification for component inside normal block with z-index = 1 should be bellow block with z-index 500
