vimvixen-console-frame covers some websites

[josepmdc]

I'm opening this issue because:

• I'll report a bug
• I'll propose a new feature

Description

In some websites vim vixen's iframe "vimvixen-console-frame" covers the page completely, leaving it unusable unless the iframe is removed from developer tools. An example of such websites is itsfoss.com.

Failure Information (for bugs)

When the page loads it looks good until vim vixen's iframe loads and covers the page, making it unusable.

Steps to Reproduce

1. Load a website, like https://itsfoss.com for example
2. Wait for a second until vim vixen is loaded
3. The page gets covered by the iframe

System configuration

• Operating system: Arch Linux x86_64 (Also tested on Manjaro Linux)
• Firefox version: 85.0
• Vim-Vixen version: 0.32

Console logs

No logs
