`body:has(#…-modal[style*="display: flex"]) #…-tooltip-bubble` made the
browser re-check the whole page on every inline-style change anywhere.
ComfyUI moves every DOM widget (text boxes) on each pan/zoom frame, so every
frame paid for it, with the browser closed too, and much more with plugins
that add DOM per widget (ComfyUI Prompt Assistant).
Measured in ComfyUI (frontend 1.53.6, Chromium) panning a 300-node
workflow for 120 frames, style recalculation in total:
- no plugins 60 ms; AMB 690 ms -> 63 ms
- AMB + Prompt Assistant 2300 ms (~19 ms/frame) -> 86 ms (PA alone 80 ms)
The rule was redundant: both popups hide the tooltip when they open and
showSharedTooltip refuses while either is open (checked in the browser).
Cache-busting versions bumped so browsers load the new stylesheet.
