Gallery question: multiple img w/ different condition - BUG?

[saguaro]

I am having some difficulties with an image gallery. The buttons are supposed to contain multiple images, one for each variation of the background.

Code: Select all

    g.button("Intro")
    g.condition("persistent.introextra01 or persistent.introextra02 or persistent.introextra03")
    g.image("introextra01")
    g.condition("persistent.introextra01")    
    g.image("introextra02")
    g.condition("persistent.introextra02")
    g.image("introextra03")
    g.condition("persistent.introextra03") 

Unfortunately, if the buttons are unlocked out of order (for example, the player encounters introextra02 first), the code will only display the placeholder text ("Image 01 of 03 is locked").

Unlocking 02 and 03 will result in showing the placeholder image and image 02.

I looked at 00gallery.rpy but I am not sure what change I could make to resolve this so the player can see any image based on a condition regardless of if the earlier images are unlocked. Can anyone advise?

Having done some testing, I believe this is a bug. In case anyone can help me find a workaround, I have attached a demo. Simply drop into a new project.

Note buttons 2, 3, and 6 -- all three return to the gallery screen after displaying the image 1 placeholder. The other buttons show all the unlocked images associated with that button.
