JS: Performance fix for chrome

Holy performance killer batman! Chrome was updating nodelists on
every change instead of batching them like firefox resulting in
exponentially worse performance. (Like "This fix made it go from
40 minutes to 7 seconds" exponentially)

CSS: Set contain on kint dumps to help client side performance

The contain and content-visibility properties are very new and
can actually break rendering entirely in different circumstances
for different browsers.

For now we'll stick to good old display:none and just hope contain
implementations get good enough to give us some perf down the line.

Use more null coalescing
