cell line numbers fail to display for all executed cells

Did a clean windows install on Oct 11. Followed that day or the next by anaconda windows install. Version 5.0.0 of ipykernel was installed. When running scripts manually or with Restart&Run - cells were being executed in wrong order and some skipped. Could only control by running each cell and waiting until it was completed. See #362

Installed (conda install ipykernel) version 5.0.1 today. For first script I ran, the first 4 cells executed and the line numbers correct.

For the remaining 6 the * remains even after cell execution. If the script is interrupted the correct cell line numbers appear in place of the *.

Ran a second script - first 18 displayed correct cell number after execution. 3 cells have executed and * still present. The 4th still running and than kernel dies. Contrary to message it never restarts. I always restart Windows at this point.

Win 10 Home 1803 build 17134.345
conda 4.5.11
ipykernel 5.1.0
python 3.6.6

Start by reproducing the execution-count and kernel-status behavior on Windows using the reported Python, conda, and ipykernel versions. The payload names no source files or tests, so trace how executed cells report their counts and how kernel restarts are handled. Done means executed cells consistently show their line numbers and a failed kernel actually restarts.
