Indent is not handled correctly when adding new lines.
It seems that functions/loops/etc. are not recognized until they have at
least one indented block.
For example, if you enter a newline after `func foo():`, the cursor will
not be indented. If you manually indent and add a line like `pass`,
e.g.:
```
func foo():
pass
```
now any insertions above or below `pass` will be indented correctly.
This might be an issue with the grammar, as it seems to apply to highlights
as well.
The following will not be highligted
```
func foo():
```
However, the following will be:
```
func foo():
pass
```
* Comment: use `@combined` to create just one tree per buffer
There is no need to create a tree per line/block for comments.
Should fix https://github.com/nvim-treesitter/nvim-treesitter/issues/1251
* Add injections for scss
* Fix jsonc
* Combine jsdoc
