The ID `searchGoButton` is used for the go button in Monobook. In Vector this same element has the ID `searchButton`. I'd like to consolidate the data generating Monobook and Vector.
Users can prepare for this change by using the selector
`#searchGoButton, #searchButton` instead of `#searchGoButton`
According to https://global-search.toolforge.org/?q=searchGoButton&namespaces=&title= 728 pages would be impacted.
Changing this would require the following:
[x] Fix Wikibase to support both IDs ([[ https://gerrit.wikimedia.org/g/mediawiki/extensions/Wikibase/+/150fba975fb92e919f292ae66ad5e967dfafc730/repo/resources/wikibase.ui.entitysearch.js#118 | code ]])
[x] Preparing editors for the change via a user notice T255953
[] Renaming searchGoButton to searchButton in Modern
[x] Renaming searchGoButton to searchButton in Monobook
