Assigning to the only owner of the component

 Issue 869470  has been merged into this issue.

I've detected 2 new tests that have crashed multiple times in the past 14 runs:

* external/wpt/background-fetch/fetch.https.window.html [x4]
* http/tests/background_fetch/block-cors-preflights.https.html [x4]

Adding disables for these two (see  Issue 873045 ).
