`/scheduler/reports` are broken because of newer version of jquery.flot
The graphs are broken.
This is because of newer version of flot library that is shipped with debian 11. (
Newer version no longer allows custom HTML tags in the axis ticks text.
Unfortunately there is easy way to fix that that I found. (I only found people complain that it is no longer possible)
The quick fix would be to remove the URL and replace them with simple values but this would have a functionality loss.
