Un-nest the dock panels: crisp in Firefox, and side by side

The console panel lived inside the bar, so its centring translate and its
backdrop filter were both nested inside the bar's own — a half-pixel offset
under a blurred layer, which is what Gecko was rasterising the text through.
Panels and bar are siblings in one column now.

That column is also what the issues list needed: it was a popover anchored to
its trigger, opaque where the console is frosted and landing on top of it when
both were open. It is the same panel now, the same width, in the same row.
