Default layout snap not used if video exists

[Chadnaut]

local a = fe.add_artwork("snap", 0, 0, 400, 400);
a.video_flags = Vid.ImagesOnly;

local t = fe.add_text("[Name]", 0, 0, 400, 400);
t.char_size = 30;

Emulator settings: snap contains two paths, one for images, one for videos.

Scenario 1:

• Image missing, video exists
• Default in snap folder only (ie: ../mame/snap/Mame.png)
• Default is displayed

Scenario 2:

• Image missing, video exists
• Default in layout folder only (ie: ../layouts/my_layout/snap.png)
• Default is NOT displayed <-- should behave as above?

Scenario 3:

• Snap missing, video missing
• Default in layout folder only (ie: ../layouts/my_layout/snap.png)
• Default is displayed <-- only when ALL snap assets unavailable

Same behavior in AM 2.7.0
