Labels with HTML sometimes render as Empty (reproducible in viz.js)
Steps to reproduce
Load the attached DOT file in viz-js.com, and try a few minor edits (spaces). From time to time, one of the nodes will be displayed without label. You can also watch the attached video clip for a demonstration. Originally reported under , but the hpcc-systems developer didn't think it was an issue on his side.
The problem is somehow related to a combination of clusters and the use of HTML for labels.
OS Version
I am using the HPCC wasm library; which worked fine in the 1.xx versions, but since 2.xx has this problem. Since I can also reproduce the problem with viz-js, the problem is most likely in the graphviz library itself.
I didn't try running the commandline binary of Graphviz yet.
