[Feature] Ability to compare expected & actual Image side by side quickly for faster bug identification.

[kp-abhishek-agrawal]

Playwright's visual regression testing is really good & fast & we are using it widely. The only problem I am having now is when I need to compare actual vs. Expected image for very long page, I have to scroll up & click on diff to see the difference. Also, there is no option for side by side comparison for actual vs expected. I wanted to request for side by side comparison & onClick feature to see diff image on actual snapshot side so that I don't have to scroll up again & again. (something very similar to Percy tool). This really helps see differences faster & reduce the time to log bugs in case we are visually testing tons of pages.
