Regexp matching on item tag doesn't work when interface description contains a comma ","

[hairy-frogfish]

Hi,
I'm using grafana 11.4, zabbix plugin v 4.6 and zabbix version 6.0 with mysql DB.

I'm aiming to make a graph in grafana that contains all interfaces that have a description containing 'somestring'.

In grafanas edit-panel, selecting a specific interface does works correctly.
Selecting with a regexp match on interface name (e.g /port-channel/) works (all port channels are displayed as individual graph items... great!)

Selecting on interface description (e.g. /somestring/) works in principle, but breaks for interface descriptions containing a literal comma (",")

That means, only interfaces are selected, where items.name looks like
Interface Ethernet1/1(bla somestring blubb)
are matched, while
Interface Ethernet1/2(bla somestring blubb, bla)
is not matched (although the description is shown correctly in the drop down list for the item tag).

Unfortunately it's beyond my magic, to debug the reason for this behaviour.

Best regards
S.
