[css-grid-3][masonry] Performance concerns wrt intrinsic track sizing in grid axis #10266

@fantasai

Description

@fantasai

Blink raised concerns with quadratic performance of intrinsic track sizing with spanning items, filing this issue to track that item specifically (as opposed to the exponential issue tracked in #9326). See comments in #8206 and #9041

I'm also concerned that considering all non-explicitly placed grid items in every posible start position will likely result in bad performance, that's a guaranteed quadratic algorithm.

The proposal outlined to address the placement/sizing mismatch in #8206 (comment) could result in approximately quadratic performance, even in very simple cases.
