### System information

Steam OS Holo, Steam Deck

### Issue description

Using a `[br]` tag at the end of a line in a documentation comment adds an additional space at the beginning of the following line:

![image](https://user-images.githubusercontent.com/857660/236700815-c78a317f-cdf8-4f3c-8489-41f9559ffe6d.png)


### Steps to reproduce

The script below is what I used to generate the image above:

```gdscript
class_name Test
extends Node

## High-level description
##
## First line of detail.[br]
## Second line of detail.
```

Removing the space between `##` and `Second` doesn't change the output.

The only workaround I've found so far is to remove the linebreak after the `[br]` tag, but this makes the documentation comments harder to read in the editor:

```gdscript
class_name Test
extends Node

## High-level description
##
## First line of detail.[br]Second line of detail.
```
