fix: Fix initial glitch (Context solution)

[alexanderGugel]

Alternative to #185 using Context.

Change to the way we retrieve the Context Size: getSize method has been moved from DOMRenderer to Context.

👍

I still believe that we need to figure out how to do this using mount state, but in the meanwhile this is good.

[alexanderGugel]

@DnMllr Are you ok with this? I think it's more intuitive to fetch the size from the actual context then the DOMRenderer. Sorry, didn't mean to put this in this PR.

[DnMllr]

�I think this is good.

[michaelobriena]

Looks like I found a bug in this, trying to repro.

[alexanderGugel]

@michaelobriena Rebased. Can you reproduce the bug?

[michaelobriena]

@alexanderGugel @pilwon 's example in #160 shows that it this solution breaks with first frame renderSize

Edit: Talked with Alex offline and confirmed that this solution did indeed cause different issues with renderSize.

[alexanderGugel]

@michaelobriena I'm confused. This PR wasn't meant to address #160 . This PR only fixes the initial glitch. @browles solution hasn't been merged in yet.

IMO having the two PRs together should fix both issues, but I need to verify that.

[alexanderGugel]

@michaelobriena Switched to naive display: 'none' solution. Needs more testing before merge.

[michaelobriena]

I want to test this more, moving to the next minor.

Sounds like this will be merged in very soon?

[michaelobriena]

@alexanderGugel this does not fix the issue. Run this branch with the seed project.

[alexanderGugel]

@michaelobriena Are you sure you tested this properly? There is no way to test this using the seed project..... and everything works fine there. Please double check or be more specific.

[michaelobriena]

Yes I tested this. If you check out your branch and then run the seed code you will see the spinning logo in the top left for a frame.

[alexanderGugel]

This conflicts with some other changes. Not sure why. I think I haven't rebased this properly.

[alexanderGugel]

Closing. Will reopen tomorrow.
