836231 - Can't input Japanese using Microsoft IME in a contenditable field

Status: RESOLVED WORKSFORME

(Core :: DOM: Events, defect)

Description

[Wiktor Walc]

Attachment: simplified_tc.html

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0
Build ID: 20130116073211

Steps to reproduce:

In some cases, when using a contenteditable body inside an iframe, user is not able to type Japanese.

The attached sample can be used to reproduce the issue.
1. Make sure that Japanese keyboard is selected in MS Windows (Japanese Microsoft IME "Input Method Editor" / Hiragana).
2. When the page loads, start typing (do not click the yellow editing area first).
3. Hint: letters y/u/i/o/p should result in Japanese output, but it does not happen.
4. Click outside the editing area and click back inside of it, type again. Note that now the Japanese keyboard works.

The attached sample might seem to be an edge case, but we're facing a very same issue in CKEditor 3.x (http://dev.ckeditor.com/ticket/9749), which is still widely used:

1. Make sure that Japanese keyboard is selected in MS Windows (Japanese Microsoft IME "Input Method Editor" / Hiragana).
2. Start typing in the editor (see that the text is entered into the editor in English)
3. Click outside the editor
4. Click into the editing area again and start typing, now Japanese works.
There is a bug report for CKEditor: http://dev.ckeditor.com/ticket/9749
User is not able to type Japanese when editor is focused on startup.
The text is entered into the editor in English and it is not possible to switch the input mode to Japanese. 

The instruction on how to set up keyboard in Japanese is available in http://dev.ckeditor.com/ticket/9749



Actual results:

The text is entered into the editor in English although Japanese IME was selected.


Expected results:

When Japanese IME is selected, user should type Japanese.

Yes, this is reproducible in CKEditor 3.x only. However, the attached simplified_tc.html sample is not using CKEditor at all (the sample itself may not reflect exactly what CKEditor internally does, but maybe at least it will be easier to track down the source of the problem thanks to it).

Problems are as follows
1. Caret is missing
2. Spellcheck does not work
3. IME does not work

Reporter, could you test this using the latest Nightly?  I cannot reproduce this on the latest.

Comment 6

[Wiktor Walc]

I'm no longer able to reproduce it either, both in nightly 47.0a1 (2016-02-21) and latest stable (44.0.2).
