Issue with "Transition to the Lightning Editor for Email Composers in Email-to-Case" release update is enabled. A case has an email where there is an embedded logo like in the signature. When the user copies the email content(ctrl A and C) to paste in a new email window in Salesforce it only copies the logo but no other content. If you turn this release update off then you can copy and paste the email content in a new email window with it pasting all the content not just the logo. Is there any fix for this with turning on the release update?
I opened a case with support. They researched with product management and said it is a known limitation. They will have it fixed before this update is enforced, currently there is no date for enforcement.
