Time Tracking URL bug

[assom974]

Version(s) affected: 3.8.2

PHP Version: PHP 7.1.32-1

Description
When opening an issue with a 'Time Tracking' entry, if you click on the time tracking entry you get an error message:
"Sorry, you are not allowed to access this page."
With the URL pointing to :
eventum.*****.com/time_tracking.php?ttr_id=undefined
But if you right-click and choose open in new tab/window the URL is generated correctly and it works:
http://eventum.*****.com/time_tracking.php?ttr_id=3480

How to reproduce
Open an existing issue that has a time tracking entry.
Click on the URL of the time tracking entry and the pop-up will give the error message:
"Sorry, you are not allowed to access this page."

Possible Solution
Right-click and open on a new tab/window fix it.

Additional context
I tried replicating the issue with the latest Eventum version of 3.8.15(on my test VM) and the same problem occurs.

Looks like it's changed in the browser itself:

• https://github.com/eventum/eventum/blob/v3.9.3/res/assets/scripts/pages/IssueView.js#L442

this expands to <p> tag what's inside <a> somewhy:

-        const ttr_id = $target.data('ttr-id');
+        const ttr_id = $target.closest('a').data('ttr-id');
