Fix: overflow expanding title in entry header

[math-GH]

Before

Config article icons (default):

(A) mouse over an article expands the title with overlapping the date

If some icons are disabled

(B) The title expanding is buggy and in some cases the title does not expand - it shrinks

If the summary is enabled

(C) The title cannot be expanded by mouse over

After

(A) Similar as before

(B) The title does not shrinks while hovering

(C) The title expands

Pull request checklist:

• clear commit messages
• code manually tested

Ups, regression: the date is always visible, also on small screen, making titles nearly impossible to read on mobile

I forgot to commit a little change :/

Another regression from here I think: the hover colour of the date in dark theme (Origine) is darker than non-hover, which is likely wrong:

That is not an regression, it is by purpose. The font color gets an opacity for a better title overlapping view.

Maybe we could improve the opacity

Ah right, but when there is no overlap, it looks strange. I believe it should have the same colour than the title

@math-GH This PR broke the suspension points in Dark theme by removing the dark filter on them.
Before:

After, whiter and brighter:

First I could confirm it. Font color is #888888 but the points are #cccccc

After trying something I cannot reproduce it. Strange.

Looking forward to this fix! Thanks! Ran into this issue myself and didn't think to report.
