Steps to reproduce:
- Edit some item and add new tag to the item:
- Tag name: TEST-NAME-["
- Tag value: TEST-VALUE-']]
- Navigate to the Monitoring => Latest data.
- Ensure the right host is selected and the new tag is provided in the subfilter.
- Click the tag.
Latest data table is not displayed (see screenshot).
The tag is highlighted (as selected) in the subfilter, and the latest data is correctly filtered.
Similar behavior has been observed in Monitoring => Hosts => Graphs section.
