Nice catch. 👍 Are you using Firefox? I can reproduce it with Firefox only, Safari and Chrome are fine. Looks like the height is not properly computed once the node attached to the DOM. ---

I use chrome and laptop screen with 125% zoom in win11. The resolution is 1920x1080. If I change the screen to 100% size, it is normal, but it is too small for the laptop screen. I usually use (also recommended by the system) 125%. ![image](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/2X/4/4fab7d3ec74469c63e81aef9def2691c4a35ccf0.jpeg) ![image](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/2X/0/0039ce51c2bbe3a44d16f0fb3ae26b3108a01a43.jpeg) I hope my information is useful ---

Ah cool to know, thanks for the feedback. I just tested locally (I’m on Mac) the 125% zoom with Chrome and the fix. Result was ok, therefore I would say the fix does definitely looks good. Please let me know once next version proposal is executed if it would not be the case. ![Capture d’écran 2023-02-18 à 12.45.55](https://us1.discourse-cdn.com/flex023/uploads/dfn/original/2X/7/70e01c8717589347de015b47ebad75cd4d54bf8c.jpeg) ---
