Python test shows spinning icon

[astrozot]

Environment data

• VS Code version: 1.39.0
• Extension version (available under the Extensions sidebar): 2019.10.41019
• OS and version: Mac OS 10.14.6
• Python version (& distribution if applicable, e.g. Anaconda): Python 3.7.1 (Anaconda 4.6.11)
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): N/A
• Relevant/affected Python packages and their versions: All
• Jedi or Language Server? (i.e. what is "python.jediEnabled" set to; more info How to update the language server to the latest stable version #3977): No

Expected behaviour

When running a test, I expect to see a spinning icon disappear after the test is completed, to show a green or red icon depending on the result of the text.

Actual behaviour

The spinning icon keeps spinning.

Steps to reproduce:

1. Within a workspace with python test units, run any test
2. The spinning icon will start to appear (and in my case will not disappear)
3. At the same time, the Console shows the error (see also below)

[renderer1] [error] TreeError [CustomView] Data tree node not found: [object Object]: Error: TreeError [CustomView] Data tree node not found: [object Object]

[astrozot]

Quick update: the same bug is present in the insider (daily) version of the Python VSCode extension, used within the insider version of VSCode.

[astrozot]

Not sure anymore what is happening. Downgrading to the previous version of the Python extension does not solve the issue (which, however, started to appear after the latest update). Downgrading VSCode to the August 2019 version does solve the issue.
