Summary Inline module scripts should execute / signal errors in order

See test at https://github.com/web-platform-tests/wpt/pull/45660 and spec discussion at https://github.com/whatwg/html/pull/10272. It appears WebKit delays running the script / firing the error event for a full task, instead of using microtask timing. If you believe we should use task timing instead, please let me know and we can start a spec discussion.

(Sorry, I didn't realize that editing the title would submit my half-typed comment.) We've updated the spec PR to align more with the WebKit / Chromium behavior, and use a full task instead. The updated WPTs at https://github.com/web-platform-tests/wpt/pull/45660 show that WebKit behaves almost in line with the updated spec proposal. However, for some reason when performing this sequence of events: - Insert a script with no parse error - Insert a script with a parse error WebKit seems to first fire the error event from script 2, then execute script 1.
