Please describe your issue in as much detail as possible:

When the primary storage device is nearing capacity (<= 2GB of free space), Steam notifies the user via a Low Disk Space toast. Instead of expanding from the bottom-right side of the screen, the toast can be seen floating near the bottom.

Low Disk Space :x:	Low Battery :white_check_mark: (Example)

Steps for reproducing this issue:

Deck:

1. Open the SteamOS Devkit Client (see https://partner.steamgames.com/doc/steamdeck/loadgames to setup Devkit Management Tool).
2. Select the target device and chose Remote Shell
3. Run the following command: fallocate -l 500G temp; rm temp

Desktop:

1. Launch Steam as a deck-like session via the following terminal command: gamescope -- steam -gamepadui -steamdeck.
2. In a terminal window, run the following command: fallocate -l 500G temp; rm temp

Note: Adjust the size parameter of fallocate based on your device's storage capacity.

Reproduction Rate: 5/5

Affected Platforms

• LCD: Yes
• OLED: Yes
• Desktop Deck-like session (gamescope -e -- steam -gamepadui -steamdeck): Yes
• Desktop: No. Issue is not present on either the default Steam client or Big Picture Mode.

Actual result

• Low Disk Space toast appears floating near the bottom of the screen.

Expected result

• Low Disk Space toast appears as if sliding in from the right-hand side of the screen to resemble more closely other system notification.

Notes

• This issue is not present on the similar Battery Low system notifications.
• The notification can also be re-triggered when rebooting the device.
• If the notification does not appear immediately, navigating to Steam > Settings > Storage will make it pop-up.
