Bug 67105 – REGRESSION: iframe load event resets the Japanese Input Method

• Component: Frames
• Status: RESOLVED DUPLICATE

Minimal HTML to reproduce the regression

I have noticed the issue on all Safari builds (including the final released versions) on Mac OS X 10.7 (Lion).

I have added an attachment that isolates the issue.

To reproduce:
1. Unzip and access index.html from the browser. 
2. Turn on the Japanese Input Method.
3. Enter Japanese text in the text area field.
4. Notice that whenever the iframe is refreshed, the Japanese text is reset.

Japanese text is refreshed only when the frame content is loaded. Frames that don't load correctly (i.e. wrong URL) do not clear Japanese text.

This was not an issue with the previous release of Safari, but since I only have Lion testing environment, I can't pin down exactly when the regression happened. I have tested all Webkit Nightlies that run on Lion, down to r90316, and have confirmed the regression.

Real-world issues

This is a problem when you have an iframe on a page that either refreshes or takes time to load. 
When the iframe is fully loaded, it will reset all text that has been entered in the Japanese Input Method. 
Since many webpages load advertisements as iframes, and since these are often slow or refreshed, the issue might be rather common.

Are you aware of any Web sites that are affected? That would help prioritize fixing this.

I did notice some similar behavior on the Japanese Amazon website (http://amazon.co.jp).

However, the Ad format (Flash, iframe /w JS, AJAX) changes depending on what ads are being featured. Also since this is a timing issue, it is difficult to replicate on external websites.

Hence I'm not sure if what I saw on Amazon is the exact same issue, or something else.

Simple answer, "I'm not sure".

This issue is now rather severe. It happens when updating your status on Facebook, each time they load up new ads.

Yes, thanks for the update!
