Links opening in tiny windows

When clicking on links which should open a new window, the new window is absolutely tiny.
This issue only started occurring after updating to the latest version, previously new windows opened completely fine and a normal size.
This only occurs when clicking on links that open in a new window, opening a new window in other ways creates the window in the correct size.

OS: Arch Linux
Graphical environment: Wayland
Window manager: Hyprland

I am aware that this issue could be nothing to do with Brave. But I figured it could be and as such was worth posting here until I am able to figure out the root cause of the issue.

How can this issue be reproduced:

  1. Open Brave and navigate to a website which contains a link that will open a new (separate) window, e.g. the second link on this page https://www.rapidtables.com/web/html/link/html-link-new-window.html
  2. Click on the link
  3. Link opens in a very small window

Expected result:
Link opens a new window normally such as when pressing Ctrl + N or launching Brave

Brave version: v1.70.117 64-Bit
