Toml-plugin-dependent features not working

[jclerman]

Describe the bug
Although I've seen them work previously, in PyCharm currently, I am not able to get either of the following two features to work:

• install extras and run scripts by clicking a line marker
• show a message for outdated version packages

Both of the above features are annotated in the feature-list as "Toml plugin is required". I do have that plugin installed.

To Reproduce
Steps to reproduce the behavior:

1. Install PyCharm CE 2021.2.3
2. Install Toml plugin (version 0.2.155.4114-212)
3. Install Poetry plugin (version 1.1.5-212)
4. Open project that uses poetry
5. Open pyproject.toml
6. Notice that line-marker for scripts is missing
7. Notice that warnings about outdated version packages are missing

Running poetry lock doesn't help.

Expected behavior
See above.

Screenshots

above, the line-markers should appear

above, click is outdated and should be highlighted

Environments (please complete the following information):

• IDE: PyCharm Community 2021.2.3
• OS: macOS 10.15.7
• Poetry Version 1.1.11
• Plugin version 1.1.5-212

Additional context
These features both worked in the recent past (and I miss them!). Not sure what has changed.

@jclerman
Thank you for creating this issue.
You may need poetry install after run poetry lock 🤔

Btw, This plugin is moving on PyCharm mainstream.
PyCharm 2021.3 EAP includes this poetry plugin code.

Also, The feature should be supported by JetBrains.
