Lib not Send?

[MTRNord]

Describe the bug Hi I am running this inside of a tokio thread. So it is async. It works when I dont create Cells inside of a for loop over a vec but as soon as I do that to generate the contents array I run into error[E0277]: dyn stybulate::Unstyle cannot be sent between threads safely

To Reproduce Not easily possible. But basicly it is a tokio::spawn() with a for loop inside that iterates over a vec, creates the row vec and pushes this to a previously created vec which holds all vecs,

Expected behavior It shouldnt cause thread issues

Toolchain

• Version: rustc 1.48.0 (7eac88abb 2020-11-16)
