I have been digging around the timelines and I see all this code that basically Fires on something called Frame 4:
I get Styles Recalculated and then
Styles Invalidated, and then somewhere way down the line:
Timer Installed and Animation Frame Requested.
Then A directory for Styles Recalculated which has within it Layout Invalidated.
I am overwriting many styles but I am doing the same in the desktop which is working fine.
It is particularly difficult because I can't get under the hood to debug and find the error. It's actually making our team rethink using the product, which is sad because I have grown to enjoy working with it.
