The old logic is incomplete. See the comment for the improved logic.
Fix#34011
And more fixes:
1. use empty "alt" for images, otherwise the width is not right when the
image fails to load
2. remove the "dropdown icon" patch, because it has been clearly done in
"dropdown.js" now
3. remove the "dropdown filtered item" patch, added a clear callback,
and improve the logic
4. fix global init when a node is removed and added back gain (eg: the
"cherry pick" dialog with a dropdown)
We would never update or build fomantic again, we have forked it as a
private library long time ago.
So just put the JS and CSS files in "fomantic/build" into git. And use
"import" to use them.
Remove "form.js", rewrite "tab" component.
All source code is from official Fomantic UI build. Will apply patches
in separate PRs.
