[Evolution] weird bug: mismatch between the message list and preview pane

[Francesco Porro <frapox yahoo it>]

I'm using Evolution again after years and I'm noticing a strange bug.
First, I have to say that I (manually, sob) set up several filters for
my mailinglist. They are working as aspected. Evolution moves mails
following the filter rules (I use to match the "list-id" header) to a
specific folder on the Imap server. And that works fine.

The problem rises when navigating through the folder where mails has
been moved, something weird happens: when I click on message, in the
message list, what is displayed in the preview pane is another message.
In other words: mail in the preview mismatch mail in the list. It's
simply another mail displayed. My reaction: 😳️ shock. 

I assumed that something got corrupted and I instinctively 
tried to look for a function "repair folder" or something like that, as
in Thunderbird, but I didn't find one. So I tried to "Undo
subscription" and this triggered Evolution to re-download (and
reindex?) the selected mail folder and related msg bodies.

So, I'd like to know if:
1) is this a know issue? Has anyone had the same or am I the onlyone? I
also looked on gitlab issues but didn't find one related to this one.

2) is there something better I could do as an alternative to the
workaround I tried, since I think it's not that good (efficient) to
redownload the entire content of a folder with hundreds of mails
stored.

I'm on Evolution 3.46.0 (by Flathub.org).
