• Shows the size trend in neutral color when the tooltip does show variance. See the attached video, it displays no change via color whereas in tooltip, it does show value has varied.

I tested creating a new monitor with two steps. Here are the observations:

Runs	step 1	step 2
1st	a comparison is shown despite being the 1st ever run	first successful run of step 2
2nd	step failed here, should a comparison be shown when step doesn't have data for a MIME Type	skipped
3rd	value is same as with 1st run but a 14% rise is indicated	failed
4th	value is same as with 1st and 3rd run but a 14% rise is indicated	failed
5th		failed
6th		it's the 2nd time the 2nd step has data (2nd successful run), should a comparison be shown with the previous run

Monitor used:

step('Goto IKEA', async () => {
    await page.goto('https://ikea.com');
});

step('Goto Lidl', async () => {
    if(Math.random() > 0.5) {
        await page.waitForSelector('text=Non-Exitent', { timeout: 500 });
    }
    
    await page.goto('https://lidl.com');
}) ;
