This commit fe9293b8b5 created a regression.
The problem is that dom changed a little bit.
Before it was
```
<tr class="instructions create-account-email">
<td></td>
<div id="account-email-validation" class="tip bad ember-view"></div>
<td><label>Never shown to the public.</label></td>
</tr>
```
And after we got
```
<tr class="instructions create-account-email">
<td></td>
<div id="account-email-validation" class="tip bad ember-view"> </div>
<td><label>Never shown to the public.</label></td>
</tr>
```
That small space may look like not important change.
However, now helpers are hitting that CSS rule:
```
.login-form {
.tip {
&:not(:empty) + td {
display: none;
}
}
```
To fix it, we should render template only if there is a reason - like it was before
```
if (reason) {
buffer.push(iconHTML(this.good ? "check" : "times") + " " + reason);
}
```
* FIX: remove rerenderTriggers
This is another refactoring in the multi-step process to remove all uses
of our custom Render Buffer.
Previous commit: 2290ec9e87 in this
series.
This commit affects the display of input tips. It is just a refactor and
does not change any functionality.
