v1.27.3

• Unless it's footage of total darkness, video thumbnails should no longer appear as black squares. You can also click on any video to immediately pause playback.
• Switch between multiple desktop spaces on macOS without missing anything. Signal messages won't be marked as read until the window is in focus.
• Support for Zoom In and Zoom Out on Windows and Linux.
• If you always maximize Signal Desktop on Windows, this preference will now remain in effect when the app restarts.
• We fixed a bug that sometimes prevented conversations from being displayed if the composition box contained a long draft message. We also added a few improvements around scrolling behavior and accessibility.
