Vis hangs trying to wrap awkward labels.

[sawatts]

We can set a maximum width in the attributes of a node, group, or global options, and the documentation states that the labels will wrap on spaces to keep within the limit.

I have observed that labels that do not contain spaces force the node to be wider than the maximum. Thats fine - perhaps should be mentioned in the documentation though.

However there is an issue where a label contains spaces, but also contains words which are wider than the maximum. This appears to cause Vis to hang / go into an endless loop.

The following jsbin will demonstrate this - uncomment the maximum width from the options in the code and the script will hang. This example includes:

• "Short" label should be fine.
• "Long Label with Spaces in it" is wrapped on spaces.
• "LONG_LABEL_WITHOUT_ANY_SPACES_AT_ALL" isn't wrapped and displays longer than the max.
• "Lets talk about Antidisestablishmentarianism again." goes horribly wrong when max is set!

Presumably Vis is doing a check whether there are any spaces, but isn't doing a check on the word lengths thereafter?

Interesting. this should have been fixed with #3228, but you found a combination which breaks it again.

It's the fourth which causes the infinite loop of course. The third I don't consider to be too critical, however the mentioned PR should have fixed that as well. Back to the drawing board.

Thanks for reporting!

The good news is that this has indeed been fixed with #3228:

The bad news is that this fix has not been released yet; that was my confusion in my previous comment. You'll have to wait for the next release for the fix; if this fix is of critical importance to you, I can provide you an interim build of the develop-branch.

Duplicate of #3171.

@sawatts vis.js v4.21.0 has just been released. Would you mind checking that the labels render as expected now?
