[Bug]: Picture-Glance entity takes much longer to load

[zavjah]

Description

Hi there,

I have a few picture-glance entities of my web cameras within a tabbed card and when I open the dashboard the same configuration outside a tabbed card load within a second or two while within a tabbed card it takes almost 10.

This issue might be related to #135 but I decided to start another thread, to be able to track both independently.

Cheers,
Zavjah
