This is a preliminary commit for upcoming change where we will use
"bot_creation_policy_values" like approach for many other settings where
dropdown represents the only single setting of integer type.
The previous code for ensuring the sort order of emoji choices was
correct relied on an OrderedDict structure, which isn't guaranteed to
be preserved when passed to the frontend via JSON (in fact, it isn't,
since we converted the way page_params is passed to use
sort_keys=True). Switch it to a list of dictionaries to correct this.
Fixes#13220.
Given that all links are now modals triggered by JS, the anchor links are
just invalid HTML that have no purpose. This commit refactors the HTML to
eliminate them by adding the Bootstrap-native btn-link class to maintain
styling. Fixes part of #6126.
