Description Kevin 2023-05-25 17:30:44 PDT 
## Summary

Videos that are webm format do not load in Safari if they are served with a data URI or blob URL.

## Test

I've created a test application so this is easy to reproduce and test.

Test Application URL: http://safari-webm-bug.s3-website-us-west-2.amazonaws.com/

The application has 3 test cases:

1. video source set to link where video is being hosted
2. video source set to data URI (data:video/webm;base64,base64WebmDataHere)
3. video source set to blob URL (blob:http://host-url/guidHere)

Access the test application from the following browsers:

Chrome ---| 1.✅ 2.✅ 3.✅
Firefox --| 1.✅ 2.✅ 3.✅
Edge -----| 1.✅ 2.✅ 3.✅
Opera ----| 1.✅ 2.✅ 3.✅ 
Brave ----| 1.✅ 2.✅ 3.✅
Safari ---| 1.✅ 2.❌ 3.❌
