Lua Formater swap comment line position

[fgc0109]

Lua Formater swap comment line position in code like this picture shows
after format the comment line " -- i am bottom" swap with line " logError(" i am top ") "

i think sometime this swap may cause error if i remove comment symbol

another problem:
in another file in the same foler , after format it use tab instead space ...

i set "lua.format.useTabs": false

Chinese：
格式化的时候在这种if else块里面会把注释的行和没注释的行调换位置啊！这样如果我没注意这个变化，格式化之后把注释取消了，并且两行的顺序会影响程序执行的话会导致错误的。
