Delay hiding the tooltip when mouse is moved away

[felixfbecker]

Reported in sourcegraph/sourcegraph-public-snapshot#132

• sourcegraph.com
• Chrome Version 68.0.3440.106 (Official Build) (64-bit), OSX 10.13.6

Steps to reproduce:

1. Go here: https://sourcegraph.com/github.com/src-d/go-git/-/blob/options.go#L325
2. Hover the mouse over an identifier (e.g: All attribute inside CommitOptions)
3. Quickly move the mouse towards the "Find references" button

Expected:

• Popup should remain in place and let me click on find references

Actual:

• Sometimes the popup disappear, probably because it thinks the mouse isn't hovering over the identifier anymore

I'll post a link to a video with the repro in a follow-up update.

@macraig adding this to our backlog from our prior discussion but noting this isn't a near or medium term priority for us (and has been sitting for two years it looks like).

@Joelkw Can we bump this? We've talked about this on Slack a few weeks ago (thread got deleted).

IMHO this is a critical issue because it's something a new user can run into in their first seconds of using Sourcegraph and it causes frustration.

Just discussed this on Slack and it sounds like this is @sourcegraph/extensibility's area here - is this doable in the short term?

Because @umpox asked for examples of other dev tools that have a hover tooltip: here's a video of me showing the ~same cursor movements in VS Code vs on Sourcegraph

delay_cursor_hover.mp4

You'll see that the delay in VS Code is also short and it's also possible to make the hover disappear, but it's far easier to move the cursor to the hover than it is on Sourcegraph
