Have a nice day there is a site wise-side.ru/demo/olympic , on the first screen of this site there are three 3 blocks with text that are made using the transform-style: preserve-3d, so that when the rotation was done (after 8 seconds) visibility of block volume. The display in all browsers is adequate, that is, as it should be according to the design of joxi.ru/Drlb0RgS41vRB2 But in the Mozilla somehow the middle block is positioned above the rest above joxi.ru/a2XKXEztyO1zxm . Z-index does not help here .... I can not understand why this is happening and how to solve this problem, if anyone can share their experiences or come across a similar one, please tell me what to do about it?
