Disabled line numbers reappear after toggling Zen mode

[abbioro]

• VSCode Version: 1.36.1
• OS Version: Windows_NT x64 6.1.7601

Steps to Reproduce:

1. Add the following to user config to disable line numbers in markdown files

"[markdown]": {
    "editor.lineNumbers": "off"
},

2. Open a markdown file, note that line numbers are disabled as expected
3. Activate Zen mode
4. Deactivate Zen mode
5. Line numbers reappear despite being disabled for markdown files in config

Note that this only happens if you disable line numbers for a specific mode. If line numbers are disabled globally everything works as expected and they never reappear.

Does this issue occur when all extensions are disabled?: Yes

Thanks for reporting this. The next vscode insiders will have the fix so you can try it out there.

The problem persists in 1.37.1

@crystalfp this will only be fixed in the next release, not in 1.37.1
But in 1.38.
It is available currently in vscode insiders so you can use that in the meantime. Thanks

I was still able to repo this in 8cd00a7 by adding the setting as a workspace setting

@mjbvz I can not reproduce this with a fresh user data dir on latest insiders.
Please let me know what you are doing differently than me and I will reopen.

Yeah, reproduces with @mjbvz's steps. @isidorn You aren't following the steps from the OP, e.g the setting must be specific to markdown (and a workspace setting)
