x/pkgsite: Jump To breaks the page when selecting it after clicking a page link

[katiehockman]

This bug is kind of hard to explain, but can be repro'd with these steps:

1. Navigate to https://pkg.go.dev/crypto/rand
2. Click something in the Index, e.g Prime (the URL should now be https://pkg.go.dev/crypto/rand#Prime)
3. Click the "Jump to..." (a dialogue should appear)
4. Press the back button
5. Note that the box has disappeared but the rest of the page is still greyed-out and non-interactable

I think the issue is that clicking the back button doesn't close the input box. It just takes me to the top of the page:

When I scroll to the bottom, the input box is still there:

@julieqiu , There have been few changes in css code since this issue was opened.The stylesheet was modified for issue #43840. Now both the .JumpDialog and .ShortcutsDialog stays on viewport. They don't get scrolled away when the screen is scrolled.

So now my question is - is it still necessary to close the input boxes when back button is pressed? because user can now see the boxes even after pressing back button and will know they need to close input box in order to interact with rest of the page.

Thanks for flagging this issue @Omkar76. I agree that clicking back should return you to the previous state without a grey overlay or the "jump to" dialog.
