Spotted by chance as part of T233787. If a method docblock has a `@suppress` annotation, doxygen will merge it to the previous annotation.
An example https://gerrit.wikimedia.org/g/mediawiki/core/+/5e9c40b66d41cece8f47fdef7a1905b908f86c9a/includes/MagicWordArray.php#134
```
lang=php,name=includes/MagicWordArray.php
/**
* Get an unanchored regex that does not match parameters
* @return string[]
* @suppress PhanTypeArraySuspiciousNullable False positive
*/
public function getRegex() {
```
Results in Doxygen generating:
> Get an unanchored regex that does not match parameters.
>
> **Returns**
> string[] PhanTypeArraySuspiciousNullable False positive
The `@suppress` is stripped and its content is appended to the content for the previous annotation (`@return`).
Confirmed to happen with Doxygen 1.8.16 and 1.8.13
