Large tables can overlap right sidebar
Table elements can extend beyond the primary content area of the page, overlapping with the "table of contents" component in the right sidebar.
Example here: https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runnerscache-section (under "This table lists config.toml, CLI options, and ENV variables for register.")

Expected behavior
Content in the main content area does not extend into the sidebar region. If necessary, like a large table, it should horizontally scroll within the bounds of the center column.
