Documentation improvement for computed property

It would be helpful if in the computed documentation for vue 2 and 3 that:

In a computed property, if you try to access a property on the instance in a branch that doesn’t run, then Vue won’t know about that dependency and won’t re-run when that dependency is assigned a new value. Link to original quote

Initial discussion

Example

When the IF test is TRUE, if the variables contained inside the ELSE statement and their values change, the computed is not triggered. E.g. computedInSomeCases

One way to prevent this, in case you want the computed to run always, is to use the variables outside the IF statement, like in computedAlways

computed: {
        computedInSomeCases() {
          return this.a ? this.b : this.c;
        },

        computedAlways() {
          const b_copy = this.b;
          const c_copy = this.c;
          return this.a ? b_copy : c_copy;
        },
},

data() {
   return {
     a: true,
     b: 1,
     c: 2
   };
}

Fiddle to test

Start with the computed-property documentation for Vue 2 and Vue 3, using the quoted forum explanation and the provided example as the requirements. Review how conditional dependencies are currently described, then update the relevant documentation so the behavior and the shown workaround are clear; the work is done when both versions accurately explain the example.
