TextField inside a multi sampling layer breaks rendering with OpenGL RHI backend

How to reproduce:

• Start attached qml scene with QSG_RHI_BACKEND=opengl (tested with Linux and Windows)

What happens:

• Only the text field is rendered, all other elements in the layer are not rendered.

What should happen:

• All elements inside the layer should be rendered, exactly as with the D3D11 RHI backend.

Notes:

• When removing the multi sampling, the rendering works.
• Also when removing the default text of the TextField, the rendering works.
