Windows 10 and tried in latest Chrome and Firefox
If I do the following the """ are visible in the code block and the ColumnB text is not inline with ColumnA, it looks there are two tabs.
```sql
"""
SELECT
ColumnA
, ColumnB
FROM
TableA
"""
```
If I do the following then it looks like hard linebreaks are working, ColumnB text is inline with ColumnA text but it does not render as a code block.
`sql is visible at the top and """ is visible at the bottom
"""
```sql
SELECT
ColumnA
, ColumnB
FROM
TableA
```
"""
If I remove the """ then ColumnB text is not inline with ColumnA, it looks there are two tabs.
