Robot syntax doesn't respect 4 spaces option in VS Code

[Soinisi]

Describe the bug
Is it a bug or a feature that even if tab option is 4 spaces, the plugin dynamically removes spaces when pressing tab? Tab can be anything from 1 to 4 spaces.

To Reproduce
Steps to reproduce the behavior:

1. Create empty file
2. Write *** Variables ***
3. Write [Documentation]
4. Press tab
5. Result one space

Expected behavior
Tab should add minimum of 4 spaces like other editors.

Environment (please complete the following information):

• VSCode version: 1.32.3
• Extension version: 2.5.0
• OS: [e.g. Linux/Mac/Win] : Windows

Additional context
I have tried to change global and [robot] tab settings to no avail

Might be overkill, but I have added this key binding to fix this issue:

{
        "key": "tab",
        "command": "type",
        "args": {"text": "    " },
        "when": "editorTextFocus && editorLangId == robot && !editorHasSelection",
},
