Subject: Only scroll to the compose form if it's not horizontally in the viewport (#11246)
X-Git-Url: https://git.xn--scling-oua.cat.family/?a=commitdiff_plain;h=c07cca4727041ea5a5721acbc603d4bfb45a15a6;p=mastodon.git

Only scroll to the compose form if it's not horizontally in the viewport (#11246)

Avoids jumping the scroll around vertically when giving it focus and
editing long toots.
