Describe the bug

The image on the collapse button vanishes, and the button cannot be pressed, if the auras selected do not agree on that particular key.

Do you have an error log of what happened?

This causes no errors.

To Reproduce

1. Create a non-group type aura.
2. Click on the > button to the left of `Position Settings'
3. Create another non-group type aura.
4. Select both the auras just created

Expected result:
The rendered options should resolve as collapsed, and should be changeable by clicking the > button in the header.

Actual result:
The rendered options are not collapsed, and cannot be changed. Additionally, the > does not appear.

Screenshots

Did you try having WeakAuras as the only enabled addon and everything else (especially something like ElvUI) disabled?
Naturally.

Which version of WeakAuras are you using?
1b3787b

Was it working in a previous version? If yes, which was the last good one?
Unknown. When I wrote this, I am fairly sure that I checked that this worked correctly. However, I do not clearly remember, and it has since been touched by @InfusOnWoW, so I cannot say for sure.

This is "fixed".
