Not entirely sure how to tell feed readers that the inline image is a custom emoji and should not be stretched as wide as possible.
CSS classes are meaningless and inline styles get stripped or modified. Would be nice to get something like rel=emoji going.
@Gargron maybe just give plain text to feed readers and give up on emojis?
@Gargron Will data-attribute get you going?
@Gargron readers strip width and height?
@KevinMarks Width and height can’t use non-pixel units, and 1em is what this kind of image needs. Width and height in a style attribute do indeed get stripped sometimes.
@Gargron height=16 as a fallback in the img tag may be a compromise
@Gargron you're keeping the rss dream alive!
@Gargron What if you offer them as (real) small (like 16×16px or so) images?
@Gargron lol
@Gargron It appears you just did. Whether they believe it is another story.
