- Don't import global Zotero SCSS
- I think this was always a mistake - preferences have their own
root SCSS file (preferences.scss) and don't need zotero.scss
- Don't add margins on radio or button labels
- Like above - I don't think this was correct even before the latest
button style tweaks!
- Don't add global margins
- Otherwise we start an arms race with all the other elements in the
pane - anything without a margin-inline-start will look like it's
sticking out to the left. Apply specific margins instead.
"Note format" section in "Export" tab is technically a table and is
announced as such by screen readers, which is misleading.
It also opens a menulist when a checkbox is clicked, which is
not an expected behavior and can shift focus.
This refactors the "Note format" section to be a vbox container
with <checkbox>es and labels, which is more correct semantically and
does not confuse screen readers. In addition, when a chekbox is
clicked, dispatch a "change" event instead of unnecessarily open
up a menu.
