1095165 - Extreme performance drop with `window.open(LARGE_DATA_URL) `

Status: NEW

(Core :: DOM: HTML Parser, defect)

Description

[Juriy "kangax" Zaytsev]

Opening a relatively large data:url via `window.open` makes browser (and even OS X) unresponsive. Process consumes up to 5GB of memory. Test case attached.

FWIW, Chrome simply crashes the tab when attempting to open it.

Can't attach file so here's a link — https://dl.dropboxusercontent.com/u/822184/data_url_test.html

To clarify, the data:url in question was generated when working with large (3000x3000px) textures for a 3d model used in Three.js app. Viewing such dynamically generated textures is useful for debugging; unfortunately, neither Chrome nor Firefox seem to be able to handle showing them as a standalone page (data:url in an address bar).
