Android TextInput placeholder with custom font has incorrect height

[computerjazz]

Description

TextInput placeholders that do not use the default android font and differ in their wrap point from the default font may be cut off. For example, if the default font does not wrap, and the custom font is slightly wider and does wrap to the next line, the placeholder will NOT reflect this wrapping, and the TextInput will only be one line.

Steps To Reproduce

• Create text input with placeholder string that does not wrap with default font, but does wrap with custom font.
• Second line will not be visible.

Expected Results

Placeholder should adjust height according to its font.

Snack, code example, screenshot, or link to a repository:

https://snack.expo.io/@computerjazz/textinput-android-bug

expected behavior (in this case placeholder text is long enough that it ALSO would wrap using default font)

actual behavior (placeholder text using "serif" font wraps to a 3rd line, but if it were to use the default font it would not wrap, and as a result placeholder gets cut off):

For reference, here's the same text using default font, note that it does not wrap to a 3rd line:

May I take up this issue? if it is open @computerjazz

[chrisglein]

This looks similar to lots of other TextInput line height issues that have come through: #31112 or #30666 for example. @computerjazz do either of those look the same to you?

@chrisglein the issues you linked look related, but I don't think any of these is an actual duplication of this ticket.

• re: Problem with lineHeight in TextInput #31112, my ticket is specifically about placeholder wrapping, adjusting lineHeight doesn't seem to have an effect
• re: Placeholder's TextInput breaking lines after change on Android #30666, my ticket does not have to do with respecting numberOfLines prop
