Issue with multi page layout

Hi,

I am facing an issue of page formatting which occurs in multi page layout : The columns having the plots are not sized correctly. When I refresh the page, the formatting gets fine.

I am attaching an screenshots of flexdashboard html report which has the above issue. The issue occurs on first time opening the html report. On refreshing the report, the formatting gets corrected itself (please see the screenshots).

Some notes -

1. It doesn't occur on the first page of multi-page layout
2. flexDashboard package version - 0.5
3. Browser used for opening the HTML - Chrome
4. Issue happened when I try to put a bar plot (plotly) and a table (knittr kable) in the same column. Having only the bar plots, it was fine.
   example column code -

`Column

{.no-title}

df <- ddply(issueData, c("CreatedMonth", "Status"), summarise, Count = length(IssueId))
plot_ly(df, x = ~CreatedMonth, y = ~Count, symbol = ~Status, type = 'bar') %>% layout(title = "Issue Status", showlegend = T, xaxis = list(title = '', tickangle = -45), yaxis = list(title = ''), barmode = 'stack')
df <- ddply(issueData, c("Status"), summarise, Count = length(IssueId))
knitr::kable(df)

File attached -

1. Screenshot of issue
2. Screenshot of corrected formatting after page refresh

Start by reproducing the attached multi-page flexdashboard in Chrome with a plotly bar plot and knitr kable in the same column, comparing the first load with a refresh. Inspect the generated HTML and layout behavior on the affected page; done means the columns are sized correctly without requiring a refresh.
