Description

Previously markdown-formatted text inside markdown table cells where breaking the markdown formatting. This was happening because while visiting nodes we were expecting the table to be inside a single text node.
So, when the table had formatting like | **apples** |, we were getting 3 nodes including | , apples (inside a strong type node), |.

The solution is to visit the paragraph node inside which the table resides and get all the text nodes' values into a single string. The rest of the operations remain same.
We also ignore the formatted text and convert them into plain text.

closes #4240

just a quick question: are using the wmde-markdown css class?

just a quick question: are using the wmde-markdown css class?

Searching through our codebase, it looks like we are not using it 🤔 It also appears to be a very old part of the codebase, last updated 16 months ago, so it might be something we used to have and haven't fully deprecated?

Alternatively, this might be overriding a class of a library we use.

There seems to be a testing issue and it also seems to be happening on main.

Looks like the changes are causing a testing issue that is not reproducible on main. It seems to be related to this selector and it might be because the node structure has changed?

Hey Tomasz
I suspected this particular test "should repeat back the system message" is failing and skipping it seems to pass the tests.

I ran this test manually in the main branch under the same conditions and seems like the system message is absent (screenshot below).

Can you please confirm from your side if this test is correct?
If so, is there a way to run e2e tests locally? For me, it is failing at the llm selection dropdown.

@uinstinct this should be working on main, I tested it locally last week. We have a CI step that uploads screenshots of failed tests and you can see that the system message is visible there.

CI step with screenshot upload:

First time you run the tests, you should run the e2e:all command. Subsequent times you will often be able to use e2e:quick instead and skip some of the setup.

Thanks for looking into this Tomasz!

npm run e2e:all ran correct locally.

when I am trying to run the specifically `GUI.test.js`, the before all hook seems to fail with the following error

> [email protected] e2e:test
> extest run-tests ${TEST_FILE:-'./e2e/_output/tests/GUI.test.js'} --code_settings settings.json --extensions_dir ./e2e/.test-extensions --storage ./e2e/storage

What should be the correct way to run only a single test file?

Figured it out! 🥳
We do not want to modify nodes which are not markdown tables. So added an early return.

Previous approach was removing the space between the paragraph's text nodes due to the buffer addition logic. This was because remark does not treat line breaks as nodes (or we need to make another remark plugin).
I figured it out by intentionally failing the test on main branch code and comparing the screenshots. The only difference was in line breaks.
