The page index worker applies the same changes to its own copy of the
pages, which has no file id and no components. :validate-shapes changes
then always failed there, so the worker logged "error updating page
index" and stopped updating the snap and selection indexes of that page
after any validated change. Drop :validate-shapes changes before
applying them in the worker.
