[FORMATTING] TransactSQL incorrectly formats some block comments, leading to broken statements

**Input data**

```sql
/** block comment **/
```

**Expected Output**

```sql
/** block comment **/
```

**Actual Output**

```sql
/ * * block comment * * /
```

**Usage**

This example reproduces on the sql-formatter playground. The only option that fixes the bug is enabling "dense operators", which produces this output:

```sql
/**block comment**/
```
