爲什麼標記，模式和unicode字符在谷歌瀏覽器的svg數據uri中顯示不正確？

Question

我在Mac OS X 10.6.8上使用谷歌瀏覽器版本24.0.1312.57。

在Safari 5.1.7 SVG圖像看起來是這樣的：

在Chrome中，它看起來是這樣的：

通知標記從路徑消失，具有模式的路徑現在具有黑色的填充並且unicode字符在其後面具有A.只有當圖片是谷歌瀏覽器地址欄中的數據URI時纔會發生這種情況。如果我以鉻版文件的形式打開svg圖像，它會正確顯示。

我試着把行結束了，並把它放在base64，但它似乎並沒有解決任何問題。

這是一個鉻的錯誤還是我錯過了什麼？

這裏的源SVG：

不確定標記和模式，但對於字符集，Chrome必須使用不同的默認編碼來存儲數據：URI。如果您在開始時添加了charset=UTF-8;，例如：

data:image/svg+xml;charset=UTF-8;base64,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 

...它應該正常工作！

這裏是fiddle。

編輯經過進一步檢查（re：標記和模式），看起來這是Chrome中的一個錯誤。它看起來像Chrome不正確地解釋（完全忽略？）url(#hash) SVG數據中的屬性值：當嵌入爲<object>（可能在其他情況下？）時的URI。

這裏的another fiddle對此問題進行了廣泛的測試。

一切正常，我在Safari 6.0.2，火狐18.0.2（蘋果機），火狐10.0.1（勝），歌劇12.12（MAC）和IE 9 <object>（as well as<embed>和）嵌入功能是在Chrome 24.0.1312.57（Mac/Win）或26.0.1405.0 canary（Mac）中無法正確顯示，而<img>嵌入正常工作。將URI編碼或base64編碼的數據：URI粘貼到地址欄中也不起作用。
