[Bug] "luna-tab-item"s don't display in Firefox

[MasterInQuestion]

    Tested Firefox 108.
    Regression introduced by Eruda v2.7.3.

    Likely related: #236

Use version 2.7.4 and see if it is fixed.

[MasterInQuestion]

    Fixed in v2.7.4.

    Firefox "document.body" is null error:
    I believe which shouldn't occur in current Firefox. [ https://caniuse.com/mdn-api_document_body ]

    Would you mind indicating the details causing the issue?

[surunzi]

Not a firefox bug. The root cause is that firebox does not support custom scrollbar. In that case, luna-tab will try to access document.body before it is ready.

    Thanks.
    Would you mind indicating the change that resolves the issue?

    Would you mind giving more debug info on how you located the problem?

    The diff you linked indicated the cause was "document.body"?
    Do you mean that in Firefox "document.body" would return null under certain conditions?
