IME for Japanese freezes webview inside a tab

[luixxiul]

Describe the issue you encountered:
If you enable IME for Japanese, hit some keys inside a input form on a page and the space key to select conversion candidates, the tab (under webview) freezes and accepts nothing until you close the tab.

Expected behavior:
It should not freeze

• Platform (Win7, 8, 10? macOS? Linux distro?): macOS

• Brave Version (revision SHA): 0c7a64d

• Steps to reproduce:

  1. Enable Japanese IME following the instruction here: http://redcocoon.org/cab/mysoft.html
  2. Open https://github.com/brave/browser-laptop in a new tab
  3. Select the search input area on that page
  4. Hit a to input あ
  5. Hit the space key
  6. Hit the enter key
     Then the tab freezes; you can neither clear the character nor click any links

• Any related issues:

This could not be confirmed on 0.12 series. I think this might be related with cr54 update.

Even pasting a Japanese character into the input area freezes tab.

Perhaps it is session store related? For me it is working correctly (I think, it's the first time I tried it). It does not freeze the tab. Maybe you can send me your session store file?

Please open https://github.com/brave/browser-laptop in a new tab and select the search input area here:

Also updated the STR.

I wonder if this could be fixed with ICU, I think we should hold on investigating until we confirm after the ICU fix.

[bbondy]

I did reproduce successfully though, thanks for the updated steps.

[luixxiul]

I doubt if this is related with IME because the tab also freezes after clicking "Edit Post" of a post on your facebook timeline.

I'm not quite sure if this is the same issue though.

[luixxiul]

@bbondy can this be closed to based on the ICU change?

[bbondy]

It can be closed if it is working, preview 8 which is available has the ICU fix.

[bbondy]

Seems to be working for me now, please re-open if you find it doesn't work.

[luixxiul]

It seems it has not been fixed completely.

rev 567bd73
Muon 2.0.10

[bbondy]

Could you update new steps to follow in the first comment, because the ones there that I followed worked now.

@luixxiul the gif you pasted doesn't look like native macOS Japanese input source
The picture below is what I saw following the Enable Japanese IME following the instruction here: http://redcocoon.org/cab/mysoft.html

[luixxiul]

@darkdh it's Google IME

[darkdh]

still can't reproduce on

rev: 9a98903
Muon: 2.0.11

[luixxiul]

@darkdh did you hit enter? the 5th 6th step

[luixxiul]

Ah I'm guessing the issue was resolved with Muon 2.0.11

[darkdh]

yeah, I did. updated with displaying pressed key version

[luixxiul]

Sweet :-D
