Sent Emails Remain in Drafts Folder

After sending an email that was previously saved as a draft, the email is successfully sent (appears in the "Sent" folder) but unexpectedly remains in the "Drafts" folder. This behavior is inconsistent with the expected functionality, where sent emails should be removed from the "Drafts" list.

Steps to Reproduce:

1. Create a new email and save it as a draft.

2. Open the saved draft.

3. Click the "Send" button.

4. Verify that the email appears in the "Sent" folder.

5. Navigate back to the "Drafts" folder.

6. Observe that the sent email is still present in the "Drafts" list.

Expected Behavior:

Once an email is successfully sent from the "Drafts" folder, it should be automatically removed from the "Drafts" list.

Actual Behavior:

The sent email remains visible in the "Drafts" folder even after it has been successfully sent and is present in the "Sent" folder.
