Flaky Cypress test - should handle long room address and long room name on right-panel.spec.ts

Steps to reproduce

1. Check https://cloud.cypress.io/projects/ppvnzg/runs/5dc8530c-98db-4a4a-aa4d-ab0c7dff8336/test-results/901b191b-dac6-4260-93d0-2de44d76ab7b

Outcome

What did you expect?

The test should run consistently.

What happened instead?

It sometimes fails due to the error below:

The following error originated from your application code, not from Cypress. It was caused by an unhandled promise rejection.

  > Cannot read properties of null (reading 'isValid')

When Cypress detects uncaught errors originating from your application it will automatically fail the current test.

This behavior is configurable, and you can choose to turn this off by listening to the uncaught:exception event.

Should checking its existence before clicking fix the issue, like cy.findByRole("button", { name: "Room info" }).should("exist").click();?

Introduced by matrix-org/matrix-react-sdk#10811, presumably?

Since that PR added that test, I guess it should be so
