I think we already know that ADE likes breaking lines at element borders (<span>s, <em>s, etc.), even when there is no space. This is another sample of annoying results caused by this
behaviour bug:
Code:
some text <a id="pg_123"/>and more text
When ADE thinks that it's OK to break the line between the <a> and "and", the first line ends with a
visible space. It's as if there were an but worse (an doesn't stretch, this space does.
The workaround is simple:
Code:
some text <span id="pg_123"/>and</span> more text
but I'm afraid many published books already use the first code, and look broken.
PS. I've noticed this reading in my Kobo. I'm assuming this is an ADE bug, and not Kobo-only, but I didn't test, and I could be wrong.
