From e89f919b92c766549db3e201ea540bce6ac5a076 Mon Sep 17 00:00:00 2001 From: Nick Gerleman Date: Fri, 24 Mar 2023 12:31:22 -0700 Subject: [PATCH] Minimize EditText Spans 8/9: CustomStyleSpan (#36577) Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/36577 This is part of a series of changes to minimize the number of spans committed to EditText, as a mitigation for platform issues on Samsung devices. See this [GitHub thread]( https://github.com/facebook/react-native/issues/35936#issuecomment-1411437789) for greater context on the platform behavior. This change allows us to strip CustomStyleSpan. We already set all but `fontVariant` on the underlying EditText, so we just need to route that through as well. Note that because this span is non-parcelable, it is seemingly not subject to the buggy behavior on Samsung devices of infinitely cloning the spans, but non-parcelable spans have different issues on the devices (they disappear), so moving `fontVariant` to the top-level makes sense here.
