Issue #1637 reports that resizing the underlying textarea of a Firenvim iframe can result in flashes of color. This can be particularly visible when using Firenvim with a dark colorscheme on Github in dark mode. The reason for these flashes of color is that when resizing, the iframe gets resized first and the Neovim canvas gets resized second, between these two moments, the iframe's background color can become visible if the CSS colorscheme of the iframe and of the website do not match. We fix this by ensuring that the iframe's background color is set to the background color of the Neovim colorscheme. This breaks the ability of the iframe to turn transparent when unfocused (the iframe gets dimmed instead), but given that multiple users complained about this feature, it may not be such a bad change. Closes #1637.
