Details
During composition, other browsers dispatch keydown and keyup events, that conforms to UI Events spec. We need to fix this at bug 354358. Currently, all widgets will use TextEventDispatcher soon (remaining platform is Android, but it will be fixed soon, bug 1137567). For now, we should set keyCode value and key value same as other browsers. (According to check each browser's behavior, only keydown is set to special values in simple case.)

Summary: TextEventDispatcher should set keyCode value and key value during composition → [UI Events] Widget should set keyCode value to 229 (VK_PROCESS of Windows) and key to "Process" if key event is handled by IME before dispatching keydown or keyup event
Current scope of this bug is, conforming keyCode value and key value of keydown and keyup event to UI Events spec. I.e., keyCode should be 229 (VK_PROCESS) and key should be "Process". https://w3c.github.io/uievents/#determine-keydown-keyup-keyCode https://w3c.github.io/uievents-key/#keys-composition However, currently, whether dispatching keydown and keyup event during composition behinds pref (except on Android) and on Linux, macOS and Android, we don't dispatch eKeyDown and eKeyUp during composition even if enabling the pref. This bug roughly fixes the latter issue for confirming to check if setting keyCode and key to the value. I'll file some follow up bugs for remaining issues of each widget before working on bug 354358.
FYI: Those patches won't be landed for 60 since they're too risky and changes some keyCode and key value even with current default settings (e.g., on some platforms, keyCode of keydown event fired immediately before compositionstart will be DOM_VK_PROCESSKEY). So, if you have some urgent work, please give higher priority to them.

And it's already declared by the specs. When we discussed them, WG decided to take other browsers' behavior as new standard. See comment 3 for the links to the specs.

Backout by csabou@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/32f5111c9891 Backed out 6 changesets for mochitest android perma failures on testInputConnection.
Wow, the robocop tests won't run when I specify "-b d" to the try syntax (i.e., only debug build)...
Comment on attachment 8955015 [details] Bug 1343451 - part 5: Make GeckoEditableSupport dispatch dummy eKeyDown and eKeyUp event during composition always Could you review this patch again? That was backed out due to permanent orange of mobile/android/tests/browser/robocop/src/org/mozilla/gecko/tests/testInputConnection.java (I tested trysever with "-b d -u mochitests" but robocop tests were not run even though they are grouped in "M" in treehearder). I added a new pref to dispatch keydown/keyup events even during composition for *any* web applications and the test checks only the new behavior since I'm not sure how to check the pref in the test, the new behavior should be enabled in default settings as soon as possible and also the testing part must not be broken so frequently.
