Yii 1.x imperavi redactor execCommand('strikethrough') not working - google-chrome

Question

After Chrome 58 update few features like Bold, Italic & Underline stopped working. On debugging i found that execCommand('strikethrough') is not striking the selected text.
formatMultiple: function(tag)
{
this.inline.formatConvert(tag);
this.selection.save();
document.execCommand('strikethrough'); //HERE, IT IS NOT STRIKING THE TEXT
this.$editor.find('strike').each($.proxy(function(i,s)
{
var $el = $(s);
this.inline.formatRemoveSameChildren($el, tag);
var $span;
if (this.inline.type)
{
$span = $('<span>').attr('data-redactor-tag', tag).attr('data-verified', 'redactor');
$span = this.inline.setFormat($span);
}
else
{
$span = $('<' + tag + '>').attr('data-redactor-tag', tag).attr('data-verified', 'redactor');
}
$el.replaceWith($span.html($el.contents()));
if (tag == 'span')
{
var $parent = $span.parent();
if ($parent && $parent[0].tagName == 'SPAN' && this.inline.type == 'style')
{
var arr = this.inline.value.split(';');
for (var z = 0; z < arr.length; z++)
{
if (arr[z] === '') return;
var style = arr[z].split(':');
$parent.css(style[0], '');
if (this.utils.removeEmptyAttr($parent, 'style'))
{
$parent.replaceWith($parent.contents());
}
}
}
}
}, this));
// clear text decoration
if (tag != 'span')
{
this.$editor.find(this.opts.inlineTags.join(', ')).each($.proxy(function(i,s)
{
var $el = $(s);
var property = $el.css('text-decoration');
if (property == 'line-through')
{
$el.css('text-decoration', '');
this.utils.removeEmptyAttr($el, 'style');
}
}, this));
}
if (tag != 'del')
{
var _this = this;
this.$editor.find('inline').each(function(i,s)
{
_this.utils.replaceToTag(s, 'del');
});
}
this.selection.restore();
this.code.sync();
},
I tested creating a fiddle with document.execCommand('strikethrough') and it worked. Even in browser`s console it works. Wondering what could have changed?
