Web implementation of hashValues can overflow when given too many inputs #50651
Description
The version of hashValues in lib/web_ui/build/packages/ui/src/ui/hash_codes.dart combines hash values by repeatedly multiplying a running total by a constant and then adding the next value. This can result in overflow if hashValues is given a large number of inputs.
When the underlying JavaScript number overflows it saturates to infinity. This causes hashValues to return the same infinity value for different inputs, resulting in an ineffective hash.
