            Bug ID: 203610
           Summary: [GTK] 'RemoveFormat' editing command changes style of
                    the parent block element
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcrha at redhat.com
                CC: bugs-noreply at webkitgtk.org

I do not expect the 'RemoveFormat' editing command to also influence 'style' attribute of the parent's block (div/p/...) of the active selection, but maybe I'm wrong.

Steps to reproduce:
a) open the Web Inspector of a WebKitWebView and switch to the console;
b) execute these two commands:
   document.documentElement.innerHTML = "<body><div style='text-align:right'>aaa <b>bbb <i>iii <u>uuu</u></i></b> xxx</div></body>"

   document.getSelection().setBaseAndExtent(document.body.firstElementChild.firstElementChild.firstChild, 1, document.body.firstElementChild.firstElementChild.firstElementChild.firstChild, 2)

c) it created a document with right-aligned div and selected 'bb ii' in it
d) remove the format on the selection, by executing this command:

   document.execCommand("RemoveFormat")

The outcome is that the selected text is neither bold nor italic, as expected, but the text is aligned to the left now, while it should stay aligned to the right.

It can be that it's only an overlook on the text-align style (and maybe some other), because when the div has style: "text-align:right; color:orange;", then the color is preserved, only the text-align is reset after the RemoveFormat command.
