YAML should not support tabs.

According to this: https://yaml.org/spec/1.2/spec.html#id2777534
`In YAML block styles, structure is determined by indentation. In general, indentation is defined as a zero or more space characters at the start of a line.

To maintain portability, tab characters must not be used in indentation, since different systems treat tabs differently. Note that most modern editors may be configured so that pressing the tab key results in the insertion of an appropriate number of spaces.

The amount of indentation is a presentation detail and must not be used to convey content information.

Each node must be indented further than its parent node. All sibling nodes must use the exact same indentation level. However the content of each sibling node may be further indented independently..`
Wild web developer allows us to use YAML files with tabs.

Is there any change to do in generic editor to allows convering tabs to space?

Start with the YAML specification linked in the issue and review the existing 26-comment discussion about Wild Web Developer's generic editor. Identify the editor component responsible for YAML indentation behavior; done should mean the requested tab handling is clearly defined and verified for YAML files.
