* Stop forcing SizeAwareImage containers to display:block A loaded SizeAwareImage set `display: block` as an inline style on its `.file-preview__button` container. Because an inline style beats every stylesheet rule, inline Markdown images were torn out of the text flow: the channel header, the header-change system message and any message with two images next to each other wrapped after every image, hiding the rest of the header. Only set `display` inline for the hidden state and let CSS pick the visible display mode. The surfaces that need block-level images (`.image-loaded` attachments and MM Blocks) already say so in their stylesheets, and `.file-preview__button` defaults to `inline-block`, which is what the Markdown and channel-header rules were already asking for.
