Per T85864
Fix unescaped messages
- Unescaped message massaction-newtask
- Unescaped message massaction-viewtask
And example fix can be found at https://gerrit.wikimedia.org/r/#/c/189200/2/includes/skins/Skin.php
It looks like this is for the calls:
Linker::specialLink( 'MassAction/New', 'massaction-newtask' );
Linker::specialLink( 'MassAction/View', 'massaction-viewtask' );
specialLink does wfMessage( $key )->text()
