I've found a regression report on twitter, but I forgot to report it to bugzilla, sorry.
https://twitter.com/Nymphium/status/509603095857201152

This is a regression of bug 479942. In bug 479942, we always set ' ' (U+20) to shortcut key candidate if the key event is caused by space bar.

However, some users may assign other function key to space bar. In such case, we shouldn't scroll up/down the page.

We should check WidgetKeyboardEvent::mKayNameIndex if it's value is KEY_NAME_INDEX_USE_STRING. If it's not so, that means the space bar is assigned to a function key.
Even if space key is pressed but it's assigned to a non-printable key, it shouldn't work as a space key because some users may assign Enter key or something to the space key.
