[#ZBX-24690] If the trigger description field contains a "line break" and a "-", the exported YAML format is incorrect.

This does not occur in XML, only in YAML format.
Occurred on 6.0.23 and 6.0.31.
This issue occurred with customers on 6.0.27 and 6.0.28.

Steps to reproduce:

Duplicate the ICMP Ping template and leave only the following.
- Item : ICMP ping
- Trigger : Unavailable by ICMP ping
Delete the trigger tag, add a line break and add - in the description field. (It will not be reproduced if you just put - at the end without line break)
Delete all template macros
Export the settings of the duplicated template in YAML format
Delete the duplicated template
Import the configuration file (YAML)

Result:
The following error is output

Details Import failed
Invalid tag "/zabbix_export/templates/template(1)/items/item(2)": unexpected tag "mappings".
