Issue for this PR
Closes #40691
Type of change
What does this PR do?
Allows
blob:URLs in the web UI'simg-srcandconnect-srcContent Security Policy directives.OpenCode 1.18.13 changed attachments to use blob-backed draft storage in #40207. Attachment previews load the object URL as an image, while submission fetches the object URL before converting it into a data URL.
The server CSP allowed
data:URLs but notblob:URLs, so browsers blocked both operations withblocked:csp.This keeps the change limited to the two directives used by the attachment flow and adds regression assertions for both allowances.
