MoLang fields bugs on mobile

[mchorse]

I don't know whether you're actively support mobile version, but I noticed a couple of bugs regarding mobile and math expression fields, so here is my report:

Autocomplete bug

Whenever you do an autocomplete, when you click on the suggestion it will have an extra character in the beginning. So if you've typed v.em and then I click on emitter_age, it would insert v.eemitter_age.

Cursor mismatch

When field's math expression becomes longer than its width, it starts bugging out in sense of:

1. The typing cursor sometimes mismatches what you actually type. For example, your cursor is at the end of the math expression, but it appears like this: math.sin(v.emitter_age) * (v.part|icle_random_1 * 0.5 + 0.5) where | is the cursor.
2. The horizontal scrolling width becomes limited. Even if the cursor behaves correctly, I am not able to scroll through till the end of the text field's content whenever I space-holding moving the cursor. It just gets stuck as if had overflow: hidden;.

These bugs occurred to me on iOS 16.3.1.

瀑布流这种卡片高度不固定的是不好做虚拟滚动的，虚拟滚动的前提是要知道每个卡片的高度。我有一个卡片的虚拟滚动组件： https://github.com/heikaimu/vue3-virtual-scroll
