title: R Plotly stacked or filled bar chart show not correctly aligned bars
body: <p>I do have the issue depicted below with filled or stacked bar charts using plotly. While the actual ggplot chart is perfectly aligned, I encounter the below issue in plotly. </p>
  
  
  
  <pre class="lang-r prettyprint-override"><code>library(plotly)
  
  #&gt; 
  #&gt; Attache Paket: 'plotly'
  #&gt; The following object is masked from 'package:ggplot2':
  #&gt; 
  #&gt;     last_plot
  #&gt; The following object is masked from 'package:stats':
  #&gt; 
  #&gt;     filter
  #&gt; The following object is masked from 'package:graphics':
  #&gt; 
  #&gt;     layout
  e &lt;- ggplot(mpg, aes(cty, hwy, fill = cyl))
  f &lt;- e + geom_col(position = "fill")
  f
  </code></pre>
