side_by_side is broken with LSP

[dmilith]

Description of the bug

Given that keybindings have a command using the "side_by_side" arguments like this:

{
    "command": "lsp_symbol_declaration",
    "keys": ["super+shift+e"], "context": [
          {"key": "selector", "operator": "equal", "operand": "source"}
      ],
    "args": {"side_by_side": true}
  }

is causing LSP features NOT to work in opened split window. It affects all LSP servers, it's a general issue.

Steps to reproduce

1. Start ST
2. Install any LSP package, make sure it works for your project
3. Hit your shortcut action with "side_by_side" set to true
4. Now on the split window (usually on the right) all LSP functionality is no longer enabled.

Expected behavior

All LSP functionality should work normally when side_by_side is set to true.

Actual behavior

Functionality is very limited in the split window.

That sounds like an issue with the LSP package(s). I suggest filing an issue here: https://github.com/sublimelsp/LSP

The underlying core issue that makes it an issue for LSP is #2411 . I'll make a comment there.
