HTML API: Increase HTML Processor bookmark limit to 10,000.

sirreal · sirreal · commit 78d738245d0f · 2026-02-27T15:17:26.000Z
The limit was overly conservative and bookmark exhaustion may occur on realistic documents. The increased limit allows documents with much greater depth to be safely processed. The limit is increased from 100 to 10,000. Developed in #10820. Follow-up to [61755]. Props jonsurrell, dmsnell, westonruter. See #64394. git-svn-id: https://develop.svn.wordpress.org/trunk@61756 602fd350-edb4-49c9-b593-d223f7449a82
