{ITEM.VALUE} doesn't always display multiline

[Nono]

Hi there,

I'm freshly using Zabbix 4.0.1 and I can't figure out an option or an explanation on the follow issue :
I'm sending multi-line text via zabbix_sender and I'm catching them via an item "Zabbix Trapper", type : text + a trigger showing {ITEM.VALUE} (1).
On top of that, I also have an action for this same trigger, sending a message with description {ITEM.VALUE) (2)

When I'm on my dashboard, showing the widget "Problems" with default configuration, {ITEM.VALUE} (1) don't display multiline: https://imgur.com/4vJdlpg
When a click on the respective date of this problem, the {ITEM.VALUE} (2) is showing the multiline on the right side of the event details: https://imgur.com/a/5FkyZtC

Could it be an option that i'm missing ?

Let me know if you may need any other information.

Many thanks in advance !

By "hacking" a bit the CSS (styles/blue-theme.css), I succeed to get what I wanted.
Changing line 82 from :

.link-action {

to:

.link-action {
white-space: pre-wrap;

Have the same issue with {ITEM.VALUE} multiline display. I made several triggers on SMMP Traps. Zabbix receive SNMP Traps through smnptrapd + zabbix_trap_receiver.pl script.
I can see incoming Traps in Latest Data history.
All lines of Trap are displayed.

I want to see all these lines in trigger description. I use

{{ITEM.LASTVALUE}.regsub("(.*)", \1)}

expression in description field of a trigger.

But when a trigger is launched I can see only first line in of an Snmp Trap in Problems Menu.

Is there any way to see all Trap message in Trigger description field?
