[docs] Textfield pattern property example is wrong?

[someka-vrc]

Hi, thank you for sharing the easy-to-use SDK and clear documentation.

The sample for <sdpi-textfield> in this page includes pattern="/^[a-z ,.'-]+$/i" , but this doesn't work correctly. I believe it should be pattern="^[a-z ,.'-]+$" or pattern="[a-z ,.'-]+" instead.
