/* Sizing CSS for inline images requires care, because images load
|
|
asynchronously, and browsers will unfortunately jump your
|
|
scroll position when elements load above the current
|
|
position in the message feed in a way that changes the
|
|
height of elements. (As of March 2022, both Firefox and
|
|
Chrome exhibit this problem, though in Chrome it is pretty
|
|
subtle).
|
|
|
|
We prevent this by setting a fixed height for inline
|
|
previews. 100px is chosen because we don't want images to
|
|
overwhelm conversation in message feeds, as it does in chat
|
|
tools that show images at half-screen height or larger.
|
|
|
|
If there are several images next to each other, we display
|
|
them in a grid format; the same considerations requires
|
|
that either use a scrollable region or set a fixed width
|
|
for images so that the browser statically knows whether
|
|
it'll need to overflow. We choose fixed width here. */
