Description
### How are you using the lua-language-server?
Visual Studio Code Extension (sumneko.lua)
### Which OS are you using?
Windows
### What is the issue affecting?
Formatting, Plugins
### Expected Behaviour
Syntax colouring should be preserved when using plugin.lua transformations
### Actual Behaviour
I'm having an issue with syntax colouring when using plugin.lua, note the colour of the inline `any` annotation.

### Reproduction steps
plugin.lua:
```lua
function OnSetText(uri, text)
if uri == "file:///c%3A/dev/test/annotation_test/any.lua" then
return {{
start = 15,
finish = 18,
text = " --[[@type any]]"
}}
end
```
Source file (note the new line)
```lua
local anything:any
-- new line --
```

Research direction
Reproduce the issue with the shown plugin.lua OnSetText transformation and the Lua source containing the inline any annotation, using the Visual Studio Code extension on Windows. Compare syntax colouring before and after the transformation, and consider the issue done when the inline annotation retains the expected colouring after the inserted text and following new line.
