Do not ellipsize file name

[yajo]

When hovering over calls, the file & method is ellipsized to the left, which is useless in my case (and I imagine also for others):

It shouldn't be ellipsized, or at least it should be to the right, because I think it's more interesting the file name and function name than the system path where it is found.

Hi @yajo!

I've heard this feedback from a few people now, and I think at least one version of it should be pretty easy to fix.

The relevant code to fix this is here:

speedscope/src/views/hovertip.tsx

Line 11 in ad49dac

export class Hovertip extends Component<HovertipProps, {}> {

.

I'd accept a PR to make the tooltip extend to the edge of the container with a margin

Hi, is enough to only increase TOOLTIP_WIDTH_MAX to 900?

[jlfwong]

@miso11 Sure, I'd accept a PR to do that, assuming it never overflows the window (which I don't think it should)

[jlfwong]

I'll close this for now due to #239, though I'd also be happy to take a more complete PR that does ellipsization in the middle of the string rather than the end
