Bad auto-summary when using the "wblinktitles" API call

The call creates summaries like:
/* wblinktitles-connect:2| */nowiki:B, enwiki:B
which are rendered as:
Added a language link to connect pages [↔$3]: nowiki:B, enwiki:B

Previously I tried to "fix" the internal summary. I do not do this
any more (I added a space, but that does not change anything).
Instead I removed the useless duplicate information from the
translation which is now rendered as:
Added a language link to connect pages: nowiki:B, enwiki:B
