Summary	0006192: Clicking the "Reply" button freezes Firefox browser
Description	Hello. I discovered a bug in SOGo 5.12.7.20260406-1 (Debian 12.12, nightly builds). SOGo takes a long time to generate a response when I click the "Reply" button in an email with multiple replies (see screenshots attached). The size of the SOGo JSON response is 75 MB. The size of the original email is 3.5 MB. Firefox uses two CPU cores and 3 GB of RAM to process this response. Please help fix this bug.
Steps To Reproduce	1) Open this email 2) Click "Reply" button
Additional Information	The original email without personal information is attached.
Tags	No tags attached.
