[Detect From Image], [Add Background Image] functionality not working properly in Firefox

[torrentwoo]

Describe the bug In Firefox, when using "Detect from Image", the detection result cannot be output normally for the first time (the height of the feedback area becomes zero), and the pose detection result can be output for the second time, but the node connection (or display) is wrong.

"Add Background Image" behaves the same as “Detect from Image".

To Reproduce Steps to reproduce the behavior:

1. Open SD WebUI with Firefox
2. Go to 'OpenPose Editor'
3. Click on 'Detect From Image' and 'Choose one picture'
4. See error

Expected behavior After the first detection is completed, the detection result can be output correctly.

Screenshots Initial UI (everything is normal):

First try (feedback area disappears):

Network debug info on first try (nothing wrong with backend data transfer):

Second time (feedback area restored, weird detection result output):

Network debug info on second time (backend data transfer goes normal):

Environment

• OS: Fedora 28 x86_64
• Browser: Firefox 105.0

Additional context In Chrome 104.0.5112.101, it works as expected.

After a few attempts, I found a simple workaround (without upgrading Firefox), DO IT AGAIN.
