Bug 198738 – REGRESSION (r244436): IndexedDB Uint8Array returned as ArrayBuffer

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[E.J. Daly]

Saving data in IndexedDB, with key data of type Uint8Array.

When reading the data back out, the data is of type ArrayBuffer.

Doesn't seem to affect non-keyPath fields.

For example:

Input: {
  id: Uint8Array(4),
  data: Uint8Array(8)
}

Output: {
  id: ArrayBuffer {byteLength: 4}
  data: Uint8Array(8)
}

Seeing this on Technology Preview Release 84
Not seeing this on Safari 12.1
