Subject: [PATCH 1/2] Remove upper limit on images.domains.length
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Large sites may have more than 50 external ímage sources, so better
remove the limit than setting another arbitrary limit.

This will undo part of #18217
