[Evolution] Left over Flatpak processes

[Linux Mint 19.3, Evolution 3.38 via Flatpak]

I'm not sure where the problem exists, so I'm posting here first. When
I close Evolution, I'm left with a bunch of processes that do not close
properly. Here's an example of the open processes on startup:

$ ps -ef | grep evolution
me  2527     1  0 17:53 ?        00:00:00 /usr/libexec/flatpak-bwrap --
args 33 evolution
me  2587  2527  0 17:53 ?        00:00:00 /usr/libexec/flatpak-bwrap --
args 33 evolution
me  2638  2587  0 17:53 ?        00:00:00 /bin/sh /app/bin/evolution
me  2715  2638  0 17:53 ?        00:00:00 /app/libexec/evolution-
source-registry
me  2985  2638  0 17:53 ?        00:00:00 /app/libexec/evolution-
addressbook-factory -r
me  3044  2638  0 17:53 ?        00:00:00 /app/libexec/evolution-
calendar-factory -r
me  3066  2638  1 17:53 ?        00:00:09 /app/bin/evolution.bin
me  3150  2587  0 17:53 ?        00:00:00 /app/libexec/evolution-data-
server/evolution-alarm-notify

...and after shutdown:
$ ps -ef | grep evolution
me  2587     1  0 17:53 ?        00:00:00 /usr/libexec/flatpak-bwrap --
args 33 evolution
me  2715  2587  0 17:53 ?        00:00:00 /app/libexec/evolution-
source-registry
me  2985  2587  0 17:53 ?        00:00:00 /app/libexec/evolution-
addressbook-factory -r
me  3150  2587  0 17:53 ?        00:00:00 /app/libexec/evolution-data-
server/evolution-alarm-notify

So far, when killing these processes (via 'flatpak kill
org.gnome.Evolution') and restarting Evolution, I have not had any
problems show up. I guess the question is: should I be concerned about
this? If you think this is a Flatpak-related problem, then I'll post on
their list.

P.S.: all of the minor glitches I've experienced in the past have been
fixed, so kudos to the devs.
