Multiple captions broken in 2.8.x?

Hello, all!

In WP 2.7.x, I was able to use the “[caption]” nomenclature when writing posts to insert images and their corresponding captions.

After the update to WP 2.8.1, I noticed that this feature seems to be broken when multiple “[caption]” sections are used in a single post. This appears to be a problem that was newly introduced in the 2.8 series. (Note that I upgraded directly from 2.7.1 to 2.8.1.)

For example, I could enter the following code into the post textbox when creating a post in 2.7.x:

[caption id="attachment_437" align="alignnone" width="100" caption="DESCRIPTION OF MY FIRST IMAGE HERE"]<a href="(...)Img_001.jpg"><img src="(...)Img_001-100x150.jpg" alt="DESCRIPTION OF MY FIRST IMAGE HERE" title="DESCRIPTION OF MY FIRST IMAGE HERE" width="100" height="150" class="size-thumbnail wp-image-437" /></a>[/caption][caption id="attachment_435" align="alignnone" width="100" caption="DESCRIPTION OF MY SECOND IMAGE HERE"]<a href="(...)Img_002.jpg"><img src="(...)Img_002.jpg" alt="DESCRIPTION OF MY SECOND IMAGE HERE" title="DESCRIPTION OF MY SECOND IMAGE HERE" width="100" height="150" class="size-thumbnail wp-image-435" /></a>[/caption]

In 2.7.x, this outputs two DIV sections, each containing the appropriate image and corresponding caption.

Under 2.8.x, the first DIV section (containing Img_001) is output properly, but the entire caption block for the section caption (with Img_002) is output as plaintext in the post (including the literal text “[caption]“).

Any ideas? Is this a bug or am I doing something wrong?

Thanks,
