Unable to iterate styled blocks in the current selection

[wongk]

Is your feature request related to a problem? Please describe.
I am trying to implement a "clear formatting" toolbar button. Any text selection may have several different stylings applied throughout the selection. The enriched APIs are limited to simple on and off states as it applies to each style, which cannot accommodate clearing all styling.

Describe the solution you'd like
Most rich text editors, including MDXEditor, which we are using for the web, have APIs for iterating through nodes/styled blocks within the selection. This makes it quite simple to clear the formatting on each node.

Describe alternatives you've considered
The only option at the moment appears to be manually manipulating the HTML, which is not a reasonable option unfortunately.

@wongk what about using the data provided by onChangeState event? It returns info whether any styles are active in the
current selection, so you can map them with proper toggle methods to essentially clear any styling. I know it's not node traversal but for now it should suffice.

@szydlovsky it seems that the state flags are only true when the entire selection is in the given state. for this reason, the toggle functions will enable the given style for the selection when they are called.

@wongk ah yes, now I get what you mean. We can definitely create a clearStyles method that would optionally take a selection as a parameter, without it would just clear the styling at the current selection. Would that be enough for your use-case?

@szydlovsky that would satisfy this use case, yes!
