I am trying to use cascading type parameters in a situation with an method group using the type param being passed to the component: [https://lab.razor.fyi/](https://lab.razor.fyi/#VVDNSsNAECYionMS6wMMOSUXi2e3IdKbJ6F7aim4Scaw0uxuNxuxhlx9Dd_Cx_HoE3gtSNNF2MswM8z3N7CFCafWzXVjtCLlbqx41_ZqmbudISOsaJAD5KWuCHtARFw9HrbkyK7H2XTFRpZoadtJSxXel05qxXjmO-yxJneH7aEMMMACJnPRlqKSquY7Q16S5cI5K4vOEa6Cg3_BRImG9HPC03QNEFj8jOA6CHLraT8iFpAhn8W6eKHSxdnonwUwb3oWL0RjNhTjNAM2DRiy8B8-_6uWFR5ByZEfdYo9jDcDDPnJwxlZq227vDj__vr53deXp0_RW_QH)

The same works using a lamda expression instead of the method group: [https://lab.razor.fyi/](https://lab.razor.fyi/#VVC9SsRAECZqoVOJ5wMMqZLGw9okRK6zEm6rOw7cbMawcsnsbTbiGfIOvoa9T-KTWNgKciEcbDPMDN_fDOxgJqh1C64NN9S4Gyvf2V6tcrc3ZKSVNQqAXHFJ2AMi4vrxsCVHdjPOpiu2WqGlXactlXivnOYmEdnUYY8VuTtsD2WAAZYwW8hWyVI3ldgbmiyTXDpnddE5wrUHOBpGjayJnyMRxxsAL-JnANfeIbeT7EeQeGIo0pCLF1IuzMb8iUebQqdhxDGmGS5lbbYUcRziPINk7mll_memT7yyLo-80Qk5xh5GzABDfvJwWql2dXH-_fXz-1ddnj0Fb8E_)

### Describe the solution you'd like

It would be great, if the method group variant behaves like the lambda one as i see no obvious reason why it shouldn't.

### Additional context

_No response_

Start by reproducing the method-group and lambda examples in the two linked Razor playgrounds and compare their compiler behavior. Trace the Roslyn handling of cascading type parameters and method-group binding; done means the method-group variant behaves like the lambda variant, with regression coverage for the reported case.
