Mouseover graphs not working

[Karel_Svoboda]

Hello,

mouseover graphs are not working for us in devices view:

However, when i enter any device detail, every mouseover graph works fine.

This is generated code, which does not work:
<img width="300" height="150" src="https://librenms.example.com/graph.php?from=-1d&amp;device=10&amp;type=device_bits&amp;legend=no&amp;absolute_size=0&amp;width=300&amp;height=150" alt="device_bits" class="graph-image" loading="lazy">

when we try to modify code like this, it works:
<img width="300" height="150" src="https://librenms.example.com/graph.php?from=-1d&device=10&type=device_bits&legend=no&absolute_size=0&width=300&height=150" alt="device_bits" class="graph-image" loading="lazy">

-> ./validate.php
