Reviewed by Carlos Garcia Campos.
In https://commits.webkit.org/276197@main, the flow for Wrapping/Unwrapping of
CryptoKeys for local storage was changed to early exit if the
webCryptoMasterKey is NULL.
For non apple ports the wrap/unwrap operations are passthrough and don't
actually use the master key.
Now, because the early-exit behavior, for non-apple ports, the wrap/unwrap
operations are now returning null in cases where master key is null/zero length
buffer.
Earlier they were not. That has been investigated as the likely cause for the
Whatsapp Spinner in this bug.
This change brings back that behavior for non apple ports.
