The problem is that Save As HTML operation is inappropriately getting
TimeConstrained wrapped around it because the internal method by which it works
shares an implementation with how Dynamics are evaluated (which quite
appropriately are TimeConstrained). So if the Export operation initiated by the FE is being halted mid-stream by TimeConstrained[].
So another way to work around this is to set the value of the
DynamicEvaluationTimeout option to be large enough to allow enough time to save
the HTML file. The downside to doing this is that increasing the value of this
option also increases the timeout for every Dynamic evaluation which may be in a hung state.
The problem is fixed for future incremental and major releases.
Sincerely,
John Fultz
