It's not cut off in Chrome or Firefox.
There's something wrong with computing the table preferred width and we end up layout overflowing it. removing the max-width property from the table fixes the sizing and the page is no longer scrollable horizontally. :(
Created attachment 399817 [details] A simplified tets-case From this test case, it seems that WebKit treats table layouts as "fixed" by default while other browsers don't. Maybe there's another bug open for this
I'm pretty sure this is the same as https://bugs.webkit.org/show_bug.cgi?id=109462
This is about max-width not being properly applied. This already has an open bug from 2013. *** This bug has been marked as a duplicate of bug 115156 ***
