Fix Uncaught TypeError in the event list

[MizukiTemma]

Short description

This PR fixes Uncaught TypeError which occurs when the event list is visited.

Proposed changes

• Remove the code lines which contains the cause of the error node.closest("li").

Side effects

• I didn't find the case when node.closest("li") is not null. If thre is any case it is not null, this code breaks the current behaviour 😅

Resolved issues

Fixes: #3031
