ggplotly stretch out to margins

[Vidaringa]

I don't know if this is rmarkdown issue or plotly issue. I'm writing a rmarkdown document and I have few graphs made with the ggplot2 package. Then I have one graph made with plotly.

Plotly does not respect the width of the document. I have specified the width to be 1140px. The text and ggplot graphs respect that but plotly doesn't. See screenshot attached.

How can I force plotly to be of the same width as the text?

If you're in rmarkdown, I think the best way to do it is to set the knitr chunk option to out.width='100%'? Anyways, https://community.rstudio.com/ or Stack Overflow would be a better venue for this question as this issue tracker is for bug reports and feature requests
