Flexdashboard not scrolling properly

[NickG]

Hi all,

I'm playing around with Flexdashboards, trying to see what they're capable of and what their limits are. I've come across some odd scrolling behaviour and was hoping for advice on a fix, as I haven't been able to find one online. As shown in the attached images, the vertical scrolling behaviour isn't currently correct, as it won't scroll fully to show the contents of Chart B when viewed on a small screen.

Code is attached. Apologies for not making it smaller, but I needed to replicate the issue and that involves stacking a few vertical charts. I was expecting the vertical scroll option to allow for effectively unlimited stacking of charts, so any advice would be great.

```{r}

sector_levels <- gaugeSectors(success = c(0, 40),
                              warning = c(40, 60),
                              danger = c(60, 100),
                              colors= c("red", "yellow", "green"))


g1 <- gauge(25, min = 0, max = 100, sectors = sector_levels)
g2 <- gauge(75, min = 0, max = 100, sectors = sector_levels)

###  Chart B 
```{r}
color_map <- c("4" = "red", "6" = "green", "8"  ="blue")


plot1 <- plot_ly(data = dataset, x = ~dataset$cyl, color = ~as.factor(cyl), colors = color_map,
  type = "histogram")

plot1 <- plot1 %>% layout(legend = c, xaxis = list(title = "Also a Test"))

An update that I've just noticed - if I resize the window to make it narrower, it actually starts scrolling as expected. Pic attached.

Basically, I'd just like this scrolling behaviour to remain no matter how wide I resize the window too!
