Editing a transclusion with many templates hangs the browser
Closed, DuplicatePublic8 Story Points

Description

Go to https://nl.wikipedia.org/wiki/Lijst_van_rijksmonumenten_in_Zaandam?veaction=edit and double-click the table. The browser hangs while dealing with the fact that there are 87 templates (so probably double that number of parts, because there are whitespace-only content blocks in between).

And that's only 87 rows, https://nl.wikipedia.org/wiki/Lijst_van_rijksmonumenten_in_Alkmaar has 399 rows.

I can reproduce this in latest Chrome canary. The tab becomes entirely unresponsive.

Looking at the Chrome task manager I see the process is consuming 102% CPU and memory usage 520M and growing.
