Design and plan, then implementation: include the details title in
selectableTextItems, restore V2 text selection in the rich bubble,
drop the InstantPageMultiTextAdapter init parameter-name split, and
split LinkHighlightingNode modern-path groups on disjoint rects.
Also includes the IP V2 inline-formula baseline alignment design doc.
drawRectsImageContent's modern path computed nextRadius and
prevRadius as min(outerRadius, floor(|Δx| * 0.5)). When |Δx| < 2
the floor produces 0 and the addArc call becomes a no-op,
leaving an unsmoothed corner at the stair-step. Replace floor
with ceil so any non-zero edge mismatch rounds up to at least
1 px. Exact-equality cases (Δx == 0) are unaffected — they take
the else branch with a straight addLine.

In drawRectsImageContent's modern path the snap loop runs midY
trimming first, leaving rects[i].maxY == rects[i+1].minY for
adjacent line rects. The X-edge snap guard then evaluated
rects[i].insetBy(dx: 0.0, dy: 1.0).intersects(rects[i+1]) — but
positive dy shrinks the rect, so after the trim the guarded
rectangle no longer intersects its neighbor (CGRect.intersects
requires positive-area overlap). Flip dy to -1.0 so the temp
rect grows and touching neighbors satisfy the guard.
