When small images are included inline within text that gets autosized, the images aren't currently resized and so end up disproportionately small. Examples of images for which this happens:
- icons indicating that clicking a link takes you to an external site
These images tend to either be included using an inline <img>, or via css e.g.:
background: url(external-link.png) right center no-repeat;
We should try to scale up these images in proportion to the text autosizing multiplier.
The hardest part may be determining what the maximum size cut-off is at which we stop doing this. Perhaps require that the image height be <= max(font-size, line-height)?
See also bug 102504, which includes an example where not scaling a background-image breaks the design, and discusses scaling of background-images.
Marking this bug Resolved WontFix because the TEXT_AUTOSIZING feature was removed in <https://trac.webkit.org/changeset/206119> (bug #162167). See bug 84186, comment 32 for more details.
