Cannot read properties of null (reading 'firstChild')

[VincentMolinie]

I got this error that happens randomly in my tests, it happens when I open the emoji picker element.
It throws the error but the emoji picker still seems to work.
It might require a little defensive programming

I'm using emoji-picker-element 1.21.1.

The error seems to be coming from here:

emoji-picker-element/src/picker/utils/calculateTextWidth.js

Line 8 in 3d84cf3

range.selectNode(node.firstChild)

Can you test in the latest version (1.21.3)? Which browser are you using? Can you share your test code? Otherwise I don't have much context to figure out where the bug is coming from...
