First reported by miya at ja.wp: write something in Japanese; press Enter; the whole line disappears. This also happens when adding a picture - in the Caption field. This does not seem to be browser or OS-specific. miya says that adding a "single-byte character" or a number at the beginning of the line, the line doesn't disappear - I don't seem able to confirm this (my tests are in Safari/X Yosemite). I'm able to reproduce the general issue at mediawiki.org (using the laptop input system for Katakana; hope I'm doing this right).
Confirmed in betalabs with hirogana, katakana(and, of course, not for romaji), and kanji. Sometime it takes two hit of Enter to delete the entered text in such languages- but the text gets deleted. For English text, 'Enter' behaves normally - a cursor goes to the new line.
