core: BOM Radar Camera not showing animation for Melbourne Radar

The problem

I have been using the BOM Weather Camera with a location “Melbourne” for a number of months with no issues.

Recently I noticed that the Melbourne radar images became static (ie not cycling through the frames as they do on the BOM website). I have tested using other browsers and the mobile app and the behavior is consistent.

If I replace the location with other sites (eg Brisbane or Sydney) these work correctly and show the animated gif cycling through the images.

The only difference I can see is that for Melbourne there are 7 frames on the BOM radar, 5 mins apart; while there are only 6 frames for Brisbane and Sydney, 6 mins apart - (checked this at the BOM website).

Tried setting the Id/Delta/Frames as per the documentation (config below) - no difference except if I set the delta at 300 (5 mins) I get a black image (rather than a static image of the radar).

Below if the animation for Melbourne (taken from an animate lovelace weather card):

Expected behavior

Below is for Brisbane with the animated radar:

Steps to reproduce

Following the integration steps here

1. Add BOM weather integration
2. Configure 2 BOM cameras - one for Melbourne and one for another city (eg Sydney or Brisbane)
3. Navigate to Lovelace and create two picture entity cards
4. Add a different BOM Camera for each card.
