Jetpack Compose Beta02, AS Canary 10

Using SelectionContainer without start padding, you can't select a word midsentence and drag the text selection handle left to include the first word -- unless you have sufficient start padding.

To reproduce:

Run the example function PartiallySelectableText() from https://developer.android.com/jetpack/compose/text#select-text on an emulator or device (I tried Pixel 2 and Pixel 4 for the former, Pixel 2 for the latter).
Select the second word of the first sentence, "text". You cannot drag the handle to include the first word, "This". (Sometimes you can get the space before "text", and even the "s" in "This", but not always.)

If you include Column (modifier = Modifier.padding(start = 25.dp)), it works as expected.
