Fixes #5558

The problem with using the elipses is that i have no idea how many digits are in there
( tho im not sure what a better solution would be, given dynamic screen sizes )

If you hover over the element you can see the full value as a tooltip.

Might it be possible to move the ellipses to the left a bit, so the least significant 3 digits (plus whatever to the right of the decimal is shown by default) is shown, per #5558? Then people can see more easily how much the balance went down after some long series of operations, in case they're using a private network to prepare something to be deployed on a network where ETH costs more.
