web sql: Useless popup

[smacker]

It's small enough end repeat content of the tab.

More context: the popup was added in #159, as a way to see the tab title when the number of tabs grows and tab titles become too small.

Let's propose improvements, but I think the initial rationale still applies and it's not useless.

it would definitely be more useful if it could show more content than right now.

another solution would be to show it only when the tab is small enough. On the screenshot, it is useless indeed.
