Bug 183228 – [mac-wk2 debug] Layout Test media/modern-media-controls/volume-support/volume-support-drag.html is a flaky failure

• Status: NEW
• Component: Media

[Ryan Haddad]

The following layout test is flaky on macOS Debug WK2

media/modern-media-controls/volume-support/volume-support-drag.html

Probable cause:

Unknown. The first failure on the dashboard blames https://trac.webkit.org/log/?verbose=on&rev=228041&stop_rev=228039, but those seem to be unrelated.
