When Using Grow on Two Widgets, Defining a Max X on One Breaks Grow Behavior

[MongooseStudios]

Describe the bug

If you have a parent frame that is told to grow on both axes, it will fill the screen as expected. If you place two widgets inside of that parent frame, and tell the both to grow, they will both consume 50% of the frame as expected. If you set a max x dimension on one of the frames, the other frame will not grow to fill the remainder of the space. This is true regardless of which of the two frames you set the max on.

How to reproduce

Run example code, observe two widgets sharing the parent frame space Un-comment one or the other max x, observe the non constrained widget still consuming roughly 50% of the space, and the other consuming space up to its max

Example code

package main

import (
	"cogentcore.org/core/core"
	"cogentcore.org/core/styles"
	"cogentcore.org/core/styles/abilities"
	"cogentcore.org/core/styles/units"
)

func main() {
	b := core.NewBody()

	container := core.NewFrame(b)
	container.Styler(func(s *styles.Style) {
		s.Grow.Set(1, 1)
		s.Border.Width.Set(units.Dp(4))
	})

	firstPane := core.NewFrame(container)
	firstPane.Styler(func(s *styles.Style) {
		s.Grow.Set(1, 1)
		s.SetAbilities(true, abilities.Clickable)
		s.Border.Width.Set(units.Dp(2))
		//s.Max.X.Dp(400)
	})

	secondPane := core.NewFrame(container)
	secondPane.Styler(func(s *styles.Style) {
		s.Grow.Set(1, 1)
		s.Border.Width.Set(units.Dp(2))
		//s.Max.X.Dp(400)
	})

	b.RunMainWindow()
}

Thank you for reporting this. I can reproduce this and we will work on fixing it when we have the time.

We fixed this issue in #1585, so this should work as expected now. Please let us know if you have any further issues.
