UI Issue: Disabled elements are styled with a strikethrough

It seems to be a bit of a UI issue that certain elements that are disabled, but you are still able to interact with, have a red strikethrough.

For example, when creating a CiviEvent, the tabs "Fees" , "Online Registration" , and "Tell a Friend" are crossed out. This is likely to appear to end users that these options are not available to them.

I realize that once you click on the tabs, you can enable these options, but users may not do this because they seem unavailable. Would it be better to just style them in a darker grey when disabled?

The red strikethrough is site-wide css:

.disabled {
text-decoration: line-through;
}
del, #crm-container .crm-is_deleted, #crm-container table.caseSelector td.status-urgent, #crm-container span.email-hold a:link, #crm-container span.email-hold a:visited, #crm-container span.do-not-email a:link, #crm-container span.email-hold a:visited, #crm-container .font-red, #crm-container .status-removed, #crm-container .disabled, #crm-container .status-overdue, #crm-container .status-fatal, #crm-container .status-hold {
color: #E43D2B !important;
}
