I am using CustomCSSforFx for a Vista-like style that I combined with "photon-australis" (colours slightly edited) for curvy tabs. Since Firefox 113 on Linux Mint with KDE Plasma 5.18.8 the curved tabs now look completely garbled; the upper row with text and close button is drawn too high and halfway disappears, while the tab itself (except the right curved rim) is missing. Please fix this.
