Root after hook is executed when onlyOn condition is met

[Ashish-chamoli002]

Cypress: 8.4.0/8.5.0
Node: 14.0.0
Typescript: 4.3.2
We have nested describe structure for our test as shown below:

describe('someTest',()=>{
   let someVar;
   after(()=>{
      someVar=null;
   });
   before(()=> {
     loginApp(...);
   });
   describe('when feature flag is on',()=>{
       before(()=>{
           onlyOn(...);
       })
       it('should....')
       describe('the user clicks on 1...')
       describe('the user clicks on 2 ...')
   })
});

what’s happening in the above is that when onlyOn is true, for some reason cypress (or something cypress does to mocha) is looking to execute an after() block immediately after the before(). It is “finding” the one at the root and executing it so the variables are prematurely null’d. So our session ends when control go for describe('the user clicks on 1...').

P.S. after() and before() are hooks.
