Splitting, merging, and splitting a text block on iOS results in two blocks with incorrect content

[dcalhoun]

Description

On iOS, splitting, merging, and splitting a text block will cause two blocks to be created, but the text is not properly split. Instead, the entirety of the text is moved to the second block.

Step-by-step reproduction instructions

1. Create a new post.
2. Add a paragraph block.
3. Add text to the paragraph.
4. Place cursor in the middle of the paragraph.
5. Tap return key.
6. Tap delete key.
7. Tap return key.

Expected behaviour

Two blocks are present. The first containing the text before the cursor place meant. The second placing the text after the cursor placement.

Actual behaviour

Two blocks are present. The first containing no text. The second placing all of the text.
