1. Go to any Special:CX page with article
2. In translation column, type in Finland
3. Select the word
4. Add link

Observed: The text now says "finland"
Expected: The text remains "Finland" with link added

This is because the string is lowercased (without explanation) at modules/source/ext.cx.source.js
141- var selection = window.getSelection().toString();
142- if ( selection ) {
143: mw.hook( 'mw.cx.select.word' ).fire( selection.toLowerCase() );
144- }
145- } );
