Bookmarked tickets no longer being highlighted?

A few of our operators have noted that when you select a ticked to be bookmarked by clicking on the ‘star’ icon, it no longer changes the colour of the star to indicate you have bookmarked it

 

It does still add the ticket to your bookmarks, but it was quite handy to see the star change colour or illuminate so you know you have saved it

I just wanted to flag it and also check if its happening to others as well
