# To set this up, first get tailscale working in an isolated linux shell:
#  1. sudo systemctl stop tailscaled.service
#  2. tailscaled -port 9993 -state tailscale-luks-setup.state -tun userspace-networking -socket ./tailscaled.sock
#  3. tailscale -socket ./tailscaled.sock up -hostname HOSTNAME-luks
#  4. tailscale -socket ./tailscaled.sock down
#  5. ctrl-c out of tailscaled
#  6 sudo systemctl start tailscaled.service
#
# Then add the .state file to your machine secrets and pass its path as tailscaleStatePath.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
