Evolution from Flathub.org at (flathub) commit ab8cf90cad6c and org.gnome.Platform/x86_64/48 at commit 0816888983b8, interestingly only when I right-click a message in the Mail view and pick Add Note (or "Edit Note" when the message has a note already), which opens a window with an editor and shortly after I start typing a text into the Plain text body the WebKitWebProcess crashes with the below backtrace. That org.gnome.Platform provides WebKitGTK 2.50.0. When I downgrade the org.gnome.Platform to commit ea15b4a059d247693f633c90db1daa43f9f52e944a1f2bb06fea1f41c57ba206, which has WebKitGTK 2.48.5, then no crash happens.
