Drilldown not opening in new tab

[mscomms]

Hi All, using the default drilldown the drilldown would open in a new tab as expected when I edited the drilldown to make the results more specific like this

<drilldown>
<condition field="community">
<set token="community_tok">$click.value$</set>
<eval token="drilldown.earliest">strptime($row._time$,"%Y-%m-%d %H:%M:%S")</eval>
<eval token="drilldown.latest">strptime($row._time$,"%Y-%m-%d %H:%M:%S") + $row._span$</eval>
<link target="_blank">search?q="index%3Dtelephony%20community%3d$community_tok$%20%7Ctimechart%20count%20by%20community&amp;earliest=$drilldown.earliest$&amp;latest=$drilldown.latest$"</link>
</condition>
</drilldown>

the drill down works as expected but it no longer opens in a new tab any ideas anyone?

I am using splunk enterprise 8.1.1

Update it looks like this is an edge issue it works fine in chrome

The dashboard is loading fine it just isn't loading in a new tab

$row._time$ is epoch time, it can't do strptime.
