kate doesn't perform a clean indentation for bash scripts, as it seems

Reproducible: Always

Steps to Reproduce:
1) Create this bash script:
---
#!/bin/bash
if [ "$1" == "this" ]; then
    echo "Please"
  echo "align"
echo "this!"
fi
---

2) Click "Tools/Clean Indentation"

Actual Results:  
No change to indentation made by kate

Expected Results:  
One might expect some alignment of the code block in between "if" and "fi", so that all three echos end up starting in one column like this:
---
#!/bin/bash
if [ "$1" == "this" ]; then
    echo "Please"
    echo "align"
    echo "this!"
fi
---

Did I misunderstand the concept of "clean indentation"?
