Qt Creator's built-in GLSL shader editor reports usage of gl_VertexIndex as an error even when using version 450 and qsb is compiling for Vulkan compatibility.

Example:

The Bug:

Qt Creator's built-in GLSL shader editor reports usage of gl_VertexIndex as an error even when using version 450 and qsb is compiling for Vulkan compatibility. This bug is purely visual; the code correctly compiles using qsb and the code works as intended when the application is run.

The Expected Outcome:

The red line should not exist under built-in keywords when those keywords are defined under the stated version at the top of the file (in this case 450 / Vulkan GLSL).
