Steps to reproduce:

Report various bugs on bugzilla, try to cross-check against other bugs, encounter unexplained flashing.

Actual results:

Unexplained flashing.

This involves the .module-subtitle element:

.module-spinner[aria-expanded="true"] ~ .module-subtitle {
opacity: 0;
}
.module-subtitle {
padding-right: 5px;
opacity: 1;
font-size: var(--font-size-small);
font-weight: normal;
transition: all .2s;
}
.module-title, .module-subtitle {
display: table-cell;
padding-left: 5px;
font-size: var(--font-size-medium);
}

So the flashing is probably a deliberate part of the page design. Firefox begins to render that in Firefox 52.

Expected results:

No flashing, no unnecessary transitions.
