> This is similar to IGNITE-9303.
> In IGNITE-9303 we missed wrong page flag check that hides this issue.
> After fixing page flag check, one of mvcc tests fails with assertion as Ignite can't lock page for write due to unknown reason: smth goes wrong with page tag.
> ExplicitWalDeltaConsistencyTest.testNotEmptyPds() fails in mvcc mode with next error
