Why doesn't expect work after a button click?

[Rich Williams]

I'm completely lost as to why this doesn't work.  If I move the expect before the button click the expect fails as expected, but if the expect is after the click it takes a while for a failure and the error says the button can't be found.  

Not my actual code, but an example that repros what I'm seeing

const { expect } = require('chai');

module.exports = {

functionName: function() {

it('functionName: expect does not work', async function() {

var drawerState = ''

//wait for the credits icon to be displayed the header

const $button = await this.app.client.$(buttonPath)

await $button.waitForExist({timeout:50000})

//expect(true).to.equal(false);    //this tells me true doesn't equal false

await $button.click();

expect(true).to.equal(false);  //this tells me that the button path can't be found

});

},

}
