Describe the bug.

When trying to use BadUsb and badusb-js on the latest version of the firmware, I am unable to properly emulate the F13-F24 keys. Support for these keys were apparently added back in March, and the code has not been removed since.
When executing a BadUsb script with F1->F24 connected to a Windows or Linux machine, with a supported keyboard input program monitoring keypresses, I am unable to register any of the F13-F24 keys.
Using other software, such as AutoHotKey, I am able to register F13-F24, so the monitoring program is not the issue. Furthermore, Windows has support for F13-F24 shortcuts, such as the default enabled Win + F21 opening settings, which I am also unable to emulate through Flipper BadUsb.
I have tried using badusb-js as well, trying F13-F24 directly, HID decimal and HID hex and no success.

Reproduction

  1. Create a BadUsb script containing F13 up to F24, each on new lines, followed by "GUI F21" on the final line
  2. Copy script to Flipper
  3. Plug Flipper into a Windows computer via USB
  4. Open a keyboard tester program that supports F13-F24
  5. Execute the BadUsb script via Flipper
  6. Notice the keypresses triggered, only the GUI key will be executed
