HTTP Get errors for several files

As noted in jupyterlab/jupyterlab#6806, when I install jupyterlab-drawio in JupyterLab 1.1.1 in a clean conda environment, I get the following errors:

[W 10:39:19.252 LabApp] 404 GET /src/css/common.css (::1) 43.88ms referer=http://localhost:8888/lab
[W 10:39:19.255 LabApp] 404 GET /src/resources/graph.txt (::1) 2.11ms referer=http://localhost:8888/lab
[W 10:39:19.277 LabApp] 404 GET /src/resources/editor.txt (::1) 2.02ms referer=http://localhost:8888/lab

I should add, when clicking on Help in the draw.io UI's Help menu this happens:
[W 18:35:52.188 LabApp] 404 GET /2/help.html (128.149.82.84) 1.70ms referer=http://localhost:8888/lab

When clicking/selecting some of the categories (e.g. UML) in the shapes panel this happens:
[W 19:11:21.024 LabApp] 404 GET /stencils/clipart/Gear_128x128.png (128.149.82.84) 2.62ms referer=http://localhost:8888/lab
Also note (may not be related to this issue) those categories do not expand unless selected a second time and the category title is stuck to read Loading....

JupyterLab v2.2.9 & jupyterlab-drawio v0.7.0, these errors still exists
