Can these be combined into an enum flag?

[shivanisha, 2016/08/22 16:15:21]

Done for readability and the fact that both of these flags are mutually
exclusive. (even though it increases the size a bit from 2 booleans to enum)

+    const bool m_blockedDocWriteScriptAsyncFetch : 1; // Non parser-blocking lowest priority fetch for the blocked script.

[Charlie Harrison, 2016/08/19 21:24:27]

The comment here doesn't really specify what the "true" or "false" states
correspond to.

[shivanisha, 2016/08/22 16:15:21]

done.
