Fixes https://github.com/flutter/flutter/issues/129862 This reverts commit cd52c0ce82b37bc9d16bea26fbd1753174c49e42. These changes were exposing an underlying bug in the DisplayListMatrixClipTracker that has now been fixed independently (https://github.com/flutter/engine/pull/43664). There are no changes to the commit being relanded here, it has been tested on the Wondrous app which demonstrated the regression before the NOP culling feature was reverted and it now works fine due to the fix of the underlying cause.
