In-page search fails on ruby-annotated text

[r12a]

This issue is applicable to all languages that use ruby markup (Chinese, Japanese, Mongolian, Korean).

If text is marked up for ruby, using the interleaved markup approach currently required by the HTML spec, a browser's in-page search no longer recognises the text. For example, if you search for 東京 on a page that has this markup:

<ruby><rb>東<rt>とう<rb>京<rt>きょう</ruby>

the search will fail to locate the word.

Note that a tabular arrangement of markup, such as

<ruby><rb>東<rb>京<rt>とう<rt>きょう</ruby>

would work fine but, although it is parsed correctly, this tabular markup is not displayed correctly by Blink or Webkit currently, and therefore the HTML specification has obsoleted the rb and rtc elements.

For more details, see this issue, which is being used to track this gap.
