The library's web renderer marked an image inline only when it was a
direct child of a paragraph with other content. A linked image sits
under a Link node, so badges such as a review bot's
`[](url) Confidence Score` header rendered as
100%-wide, 320px-tall block images in the PR panel and file preview.
Images nested in links (or emphasis) now count as inline when their
paragraph has other content; a paragraph made only of images or
image-only links still renders them as blocks. Inline images now take
the line height with automatic width instead of a line-height square,
so wide badges and photos keep their aspect ratio instead of squashing.
