Delete icon not present on mail when using a smaller window

Description

Inlined delete functionality is removed when the email list pain gets narrow.

To Reproduce…

Steps to reproduce the behavior:

  1. Open the Mailspring desktop client
  2. Widen the message list pane so it’s on a single line
  3. Hover over a message and see that a delete icon overlays the message
  4. Narrow the message list pane so it’s on two lines
  5. Hover over a message and see that the delete icon is no longer present

Expected Behavior

I’d expect the delete icon to show up in each individual message regardless of the width of the message list pane.

Setup

Additional Context

N/A

Interesting - I’d not spotted this (I’m always in the narrower view) but it’d be nice to have the functionality in both modes. Here, though (Kubuntu 21.04, deb install, dark mode), the buttons that appear over messages other than the current one don’t respect the currently selected style - they’re always light, even though I use the Dark theme.
