Vertical scrollbars appear for some messages in Dark Theme since v19.0.0
It appears that Gitter v19.0.0 introduced a regression that causes vertical scrollbars to appear for certain messages, but only in the Dark Theme. The viewport width seems to be a factor in for which messages the scrollbars appear.
This issue occurs in both the browser and the Desktop client.
In the first attached image, we can see the tiny set of scrollbars at bottom right.
In the second attached image, I've narrowed the viewport width slightly, which changes the text wrapping, and eliminates the scrollbars.
I mention the fact that width is a factor because adjusting the viewport width while testing may make it easier to spot the problem.
