hermes - 💡(How to fix) Fix [Bug]: Desktop app image preview tab overlaps with top-right UI buttons [1 pull requests]

Bug Description

In the Hermes Desktop app, when clicking on a file (e.g., an image preview) in a conversation, the image preview tab/card that appears in the top-right corner visually overlaps with the top-right UI buttons/controls of the application window.

The overlapping makes the top-right controls (such as the settings gear icon and toggle switches) partially obscured or difficult to interact with.

Additionally, after opening a file preview, the preview tab persists even when switching to a different conversation that does not contain the attachment. The preview card remains visible in the top-right corner for the new conversation, which does not make sense because the file does not exist in that conversation's context.

Steps to Reproduce

1. Open Hermes Desktop app.
2. Start or open a conversation that contains an image attachment/file.
3. Click on the image/file to open its preview.
4. Observe the top-right area of the application window.
5. Switch to a different conversation that does not contain the attachment.
6. Observe that the preview tab is still visible, even though the file does not exist in the current conversation.

Expected Behavior

• The image preview tab should be positioned such that it does not overlap with the top-right application controls (settings gear, toggles, etc.). The layout should reflow or the preview should be positioned with proper z-index / spacing to avoid UI collision.
• When switching to a different conversation, the preview tab should be dismissed or hidden, since the referenced file does not exist in the new conversation.

Actual Behavior

• The image preview tab overlaps with the top-right UI buttons, causing visual collision and potentially blocking interaction with those controls.
• The preview tab persists after switching conversations, showing a file preview for a conversation that does not contain the attachment.
