Screenshot: Link to attachment from message viewed before is shown while still fetching attachments from current message
In msgHdrView.js we handle the sizes of detached attachments to display these sizes in UI.
For users who have them on network storages (e.g. per SSHFS on internet), this means to wait for this process in case of big (e.g. 12 MByte) detached attachments and Thunderbird shows a rotating icon in the meantime for these attachment sizes.
The problem is: The UI is frozen in this time.
Maybe the code could be optimized by more async functions?
To ultimately fix this behaviour, we could provide a simple option (or hidden pref) to disabled the lookup for detached attachment sizes.
Another possibility would be to store the size of an attachment (calculated before detaching) inside the message after the content-headers:
X-Mozilla-External-Attachment-URL:
X-Mozilla-Altered:

It's almost already possible.
For https://searchfox.org/comm-central/rev/0af59a692f43286cbc0d239cafd250e33c4582ec/mail/base/content/msgHdrView.js#2801 when isFetching is true we should just skip showing the sizes.
The fetching is handled async, so the UI should not be frozen.

For clarification: Yes, the UI is not frozen but (at least in Thunderbird 68.10.0) I have following issue: After opening another message with detached attachments the attachment(s) from the previous message is/are still shown. See screenshot.

Possible to pursue post version 115?
