Steps to replicate the issue (include links if applicable):
Parse the following wikitext with the Translate extension activated:
echo "{{<translate>1x|hello</translate> stuff}}" |php bin/parse.php --integratedWhat happens?:
The template is not expanded:
<p data-parsoid='{"dsr":[0,41,0,0]}'>{{<meta typeof="mw:Annotation/translate" data-parsoid='{"dsr":[2,13,null,null]}' data-mw='{"rangeId":"mwa0","extendedRange":false,"wtOffsets":[2,13]}'/>1x|hello<meta typeof="mw:Annotation/translate/End" data-parsoid='{"dsr":[21,33,null,null]}' data-mw='{"wtOffsets":[21,33]}'/> stuff}}</p>What should have happened instead?:
The template should be expanded so that only "hello stuff" is displayed to the user (and not {{1x|hello stuff}}); the structure should round-trip correctly.
