Input from Gemini 3 Pro:
✦ Implemented the fix by overriding
createAllItemsinMainStoreto set apreventDataGenerationflag. UpdatedafterSetAmountRowsto check for this flag before generating data. Also fixed the indentation inafterSetAmountRows.

In the BigData grid example,
MainStoregenerates data wheneveramountRowsis set. When filtering, theallItemsbackup collection is created, which inherits theamountRowsconfig, triggering a redundant data generation cycle. This fix overrides thecreateAllItemshook inMainStoreto set apreventDataGenerationflag, which is then used to guard theafterSetAmountRowstrigger.
