Inspect element that only appear when other element is mouse overed/entered

Often I want to inspect an element (eg tooltip) that only appears when another element is mouse overed/entered. The element that appears, is made visible via jQuery's mouseenter event.

I can't inspect the tooltip, since the tooltip disappears when my mouse leaves the containing element.

Is there a way to pause JS events so I could hover on the element, then pause the browser's JS, and successfully inspect it?

For an example, try inspecting Twitter bootstrap's tooltips: http://getbootstrap.com/javascript/#tooltips.

It's fairly easy in Chrome 38.0.2094.0.

Here's what it'll look like:

Step-by-step:

Open the DevTools in the Sources panel

Make the tooltip appear by hovering over the button

Press F8 to freeze the page

Switch to the Elements panel and use the magnifying glass icon in the top left to select the tooltip

If the tooltip shows up because of CSS, here's what you can do in that case:

Step-by-step:

Open the DevTools

Select the triggering element in the dev tools (the link)

Right click, and select "force element state", and select ":hover"

Inspect the CSS tooltip

Both Safari's and Chrome's Web Inspector offers checkboxes where you can toggle the :active , :focus , :hover and :visited state of an element. Using those might be even easier.

There's also another tricky way to do it :

Go over the element which makes your tooltip appear.

Right click to open the contextual menu.

Move your mouse to your dev tool window and left click anywhere in the dev tool panel.

Your tooltip will stay visible, you will then be able to inspect it in the Element tab.

Tested on Chrome. Doesn't seem to work on Firefox.
