Big performance issue : @tabler/icons-webfont 3.24.0 : Firefox+Windows

[benito103e]

Description

We use tabler-icon webfont in a webapplication.
Since we upgrade from 3.1.0 to 3.24.0, our "Windows with Firefox" users experiences a huge slowdown in page loading.
Every new tab or each time you change tabs, the Reflow take more than 5sec

DomContentLoaded in ~200ms
Load : > 5.5sec

With Firefox profiler :
Layout:Reflow take >5sec
And I see a lot of

LigatureSubstitutionSubtableHelper::ReadLookupCoverage(GlyphCoverageRangeCollector&) const [dwrite.dll]
Reflow https:....
PresShell::DoFlushPendingNotifications Layout
XRE_InitChildProcess
(root)

P.S : there is no issue with Linux.

Hello @codecalm,
This issue is still there.
This is a production performance problem, not a building problem.
I'm really surprised that this problem hasn't been raised by other Issues, as it must concern several people.
Best regards.

I can't reopen this issue, so I'm creating a new one (#1327) with a very simple reproduction procedure.
