Upon selecting Selector Playground and hovering over ANY element it is not highlighted (you can barely see the selector before clicking), however clicking the element will still yield the selector.
Item being hovered over is highlighted, user can clearly see what yielded selector will cover.
Literally any test will do, even as simple as this:
describe('Random test', () => {
it('should just visit the page', () => {
cy.visit('https://www.barnebys.com/');
});
});
Steps:
Cypress 3.4.1, macOS Mojave 10.14.6, Google Chrome 75.0.3770.142
I was faced with the same issue
Cypress Version 3.4.1, Windows 10 Pro, browser Chrome 75, Electron 61

Yes , I have the same issue, looks like some resources are missing

it's seems we're meeting a big defect of the Runner UI in this Version
here is my runtime information
browserPath: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe",
browserName: "chrome",
browserVersion: "75.0.3770.142",
osName: "win32",
osVersion: "6.3.9600",
cypressVersion: "3.4.1",
hopes there are some work-around to solve this , so that we don't need waiting for the new version release,
@jennifer-shehane thanks
@Bkucera I'm guessing this is a result of the change to using webpack internally. Can you look into it?
