"Strike" button vs. ACF

[santaclaus21]

Steps to reproduce

1. toolbar (...) ,['Bold','Italic','Underline','Strike','Superscript','-','RemoveSpan','RemoveFormat'], (...)

2. config.allowedContent = 'script(*)[*]{*}; *(*); td th[colspan]{border,border-width,vertical-align,width}; table[align, cellpadding, cellspacing, border]{border,border-width,width,margin}; img[alt,!src, border, title, contenteditable]{width,height,float,margin,margin-left,margin-right,margin-top,margin-bottom,border-width}; span iframe embed object param form input select textarea[*]; article{display}; div sup sub header footer section article span table tr td th ol li p h1 h2 h3 h4 h5{font-weight,text-align,text-decoration}; a[*]{font-weight,text-decoration}; *[id]; *[contenteditable,data-animspeedid,data-autostartid,data-openonclickid,data-pictheightid,data-showcontrolid,data-showtitleid,data-slideshowid,data-speedid,data-transitiontypeid]; b i u div blockquote strong hr th em ol ul;';

3. Strike button is not present (but there is still "text-decoration" in lot of tags). W3 is: text-decoration: line-through;

Expected result

Stike button should be shown.

Actual result

Not showing STRIKE :) The way to make it visible is adding to ACF rule: strike(*)[*]{*};

The strike is represented either by s tag strike tag or span with text decoration - ​http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-coreStyles_strike.

None of definitions you have covers any of these three options.

Also a second thing to point out is that it would be a bug if just by placing a single style would unlock every plugin which is using it.
