Map shrink in MUME browser client

[co1191]

When using the browser MUME client (I check in at work and on my iPad often), whenever a long line of text occurs, the map shrinks. It does not stay stretched back again if dragged back open. I only noticed this happening recently and I have reload the game to get it back to normal.

It seems like this is called by the ResizeObserver calling handleSizeChange().
Removing this seems to fix this problem.

Additionally, the ResizeObserver seems to cause crashes (at least on my machine, Firefox on Linux).
Resizing the window sometimes results in an error "ResizeObserver loop completed with undelivered notifications", and after that the ResizeObserver stops working, resulting in the map being resizable.

I do not know if the ResizeObserver has an actual use; I cannot think of one but it has to be in the code for a reason. I might make a pull request later removing it and adding more details about these problems and we'll see where that goes.

I propose having the whitespace wrap behavior as an option in the "Options" menu, however having it disabled would result in the same map-shrink behavior as before, so that would need to be addressed as well.

Hmm, looking at #8 it seems that no nowrap is necessary for MUME to detect proper terminal dimensions upon resizing the map. Not sure where to go from here.

Perhaps some way to lock the screen unless trying to resize?

Hmm, now I'm having trouble recreating the resizing issue, even on the main site. I still get errors about the ResizeObserver, but the text wraps now.
