Difficulties selecting ruby text

[r12a]

@bobbytung reports the following:

In mono-ruby case when you select and copy certain text with mono-ruby, the last ruby texts will not be selected. For example:

After copy and paste, you will get "火ㄏㄨㄛˇ星". "ㄒㄧㄥ" is not copied.

I did a simple copy-and-paste experiment in various browsers:

• Chrome: 火ㄏㄨㄛˇ星
• Safari: 火ㄏㄨㄛˇ星ㄒㄧㄥ
• Firefox: 火星

---

Code:

<ruby>火<rt>ㄏㄨㄛˇ</rt></ruby><ruby>星<rt>ㄒㄧㄥ</rt></ruby>

[r12a]

Here are some more results, using data:text/html,<p>hello<ruby>火<rt>ㄏㄨㄛˇ</rt></ruby><ruby>星<rt>ㄒㄧㄥ</rt></ruby>bye</p> on a Mac.

In Chrome:

• triple click to select grabs everything
• double click on the 1st han character and extend to second includes the first rt (ie. 火ㄏㄨㄛˇ星) but misses the second rt (ㄒㄧㄥ), but the selection can be extended using shift+→
• selecting base characters by dragging the cursor gives the same result as previous bullet
• you can select just the 1st rt, but if you extend the selection to include the next one, it grabs the 2nd han character too (perhaps, not surprisingly)

Safari does the same, except that the actual highlight appears on the 2nd rt and not the first, which can be rather confusing.

Firefox exhibits the same highlighting behaviour as Chrome, but never pastes the rt text.

I don't have a Windows machine at the moment, so can't test Edge.
