Unwanted line break in cell

We are migrating to the newest version of DHMTLX. Several things broke (as expected) but there is one that has me stumped. One of our grid columns has a combination of text and an image that links to a pop-up balloon:

On the old version this worked fine but in the new dhtmlxGrid the image gets forces onto a new line. I’ve tried several things (like embedding the whole thing in a span where whitespace is set
to ‘nowrap’) but nothing seems to have any effect. Multiline is turned off for the table.

Screenshots for the old an new behavior are attached.

Please, try to enable the multiline content:

That works, thanks. A little counterintuitive that enabling multi-line prevents
multiple lines but I can see how that might happen.
