To add to your comment, it's kinda common to find projects that have spaces and tabs improperly mixed in the indentation. Making a quick search among the projects I have cloned, I'm seeing indentations like

  tab * 4 + space * 7 + tab * 2
  tab * 2 + space * 1 + tab * 1
  tab * 1 + space * 4 + tab * 2
  space * 16 + tab * 3 + space * 4
  tab * 4 + space * 2 + tab * 2 + space * 2
  tab * 3 + space * 3 + tab * 1 + space * 6

The code ends up looking janked unless you use the particular tab-width of the space/tab-indenter[1], which isn't always 8. It completely defeats the whole purpose of the tab indentation.

[1] On those first 2, given the odd (not even) number of spaces, it's likely that use of spaces was for alignment, but then a tab-indenter added tabs to that...
