11790	[Blink] Chrome - merging block + ACF	santaclaus21		"Maybe it's something similar to [9998] bug, but merging blocks doesn't add span, but makes something different:

Before backspace:
```
<p>&nbsp;</p>

<header>
<h2>Bus Stop Location</h2>
</header>
```

After backspace:
```
<p><strong style=""color:rgb(62, 62, 62); font-weight:700; line-height:1.85em"">Bus Stop Location</strong></p>
```

It's a little strange, because ACF is working with rules:
```
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;';
```

So even if Chromium bug [9998] - it's shouldn't happen because of ACF rules."	Bug	closed	Normal		General		duplicate
