This is a meta bug for oranges browser-chrome tests captured by the try result in bug 1193394 comment 48. In bug 1193394, we'd like to make the promise callback be executed at correct check-point right after an event handler/js callback is returned instead of at the end of a task to meet the requirement in HTML spec. We saw lots of orange factors in bc(1,2,3,4,5,6,7,8,9,10,13,14,15,16) which need further breaking down to figure out the solution.

Updated try result on all platforms is available now in bug 1193394 comment 58. The updated patches are attached as well in that bug.

testing some more fixes. https://treeherder.mozilla.org/#/jobs?repo=try&revision=06a1ff1697e9069fd4821b40040a530bfd25c1d5 https://treeherder.mozilla.org/#/jobs?repo=try&revision=e11e5839c8a8f5e1b1cd8f2fc514c5c931771c24 I'll file bugs later.

to be clear, https://treeherder.mozilla.org/#/jobs?repo=try&revision=e11e5839c8a8f5e1b1cd8f2fc514c5c931771c24 is the test with bug 1193394 patch.

there are several tests that are *not* failing, but resolves promise inside event handler. I'm wondering if it's better fixing them as well... (some of them might become intermittent, but not sure how many of them...)

(In reply to Tooru Fujisawa [:arai] from comment #6) > investigating browser/base/content/test/general/browser_ctrlTab.js, that > fails only on try turns out that.... mouse cursor is accidentally there :P

looks like there are some more non-linux issues :P

browser_tabfocus.js should be fixed in bug 1421113. browser_windowopen_reflows.js seems to be related to bug 1380465.

browser_preview_switch_print_selected.js seems to be bug 1392226, unless the patch makes it more intermittent

browser/components/preferences/in-content/tests/browser_subdialogs.js and browser/components/extensions/test/browser/test-oop-extensions/browser_ext_user_events.js might be affected by the change, while there's known intermittent. I'll investigate tomorrow.

all bugs are fixed :D
