1743697 - PGP key manager keeps even multiple selection of items after deletion, which can end up in unintended deletion of more keys.

Status: RESOLVED FIXED

(MailNews Core :: Security: OpenPGP, defect, P2)

Description

[jschoett]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:94.0) Gecko/20100101 Firefox/94.0

Steps to reproduce:

1. Open PGP key manager window
2. Select a key
3. Delete the item using the 'Del' key

Actual results:

Item is deleted but another item is selected.

Especially if more items are selected, after deletion, other items are selected randomly.

Expected results:

The selection should disappear after deletion.

!! If I selected and deleted many items, it feels like no items were deleted (if the list keeps the selection) – and then I would press 'Del' again and delete the wrong items inadvertently!

Thanks jschoett for highlighting this problem.
Confirming based on comment 0, which is clear and plausible.
This is a datalossy UX error prevention fail, which can easily induce the user to delete more keys than intended, especially in the multiple-selection scenario. Also, if you press DEL key just a little too long, it will probably proceed to delete other keys which were not originally selected. Imo reporter is right that we must not select random other keys after deleting keys from the list. Instead, selection must be cleared after deletion.

It's pretty normal behavior that the next item is selected once something (like an email in a list) is deleted.
There is also a confirmation dialog you have to click through, so very little risk of accidental duplicate deletion.

For multi-select + delete I agree there's an odd behavior after confirmation.
