Deleting text and updating paragraph alignment fails to update cursor alignment #1545
Description
Summary
This is an iOS-specific bug that @SergioEstevao caught with the recent introduction of alignment for paragraph blocks. If you select a paragraph block with text in it, delete the text in that block, and update the alignment for the text in that block, the placeholder's alignment will be updated, but the cursor itself will not update.
To Reproduce
| Step # | Step | Info |
|---|---|---|
| 1a | (Alternative a) Load a post with a paragraph block that already has text | The text can be either aligned or unaligned. The bug will not occur if you load a post with an empty paragraph block. |
| 1b | (Alternative b) Create a new block, add text to it, and then deselect and reselect that block. | Focus must leave the block in question, if you remain focused on the block the whole time then the bug will not appear. |
| 2 | Delete all the text from the paragraph block | The bug appears regardless of whether you change the alignment before deleting all the text in the block |
| 3 | Update the alignment of the empty block | The block must be empty, if you delete all the text and add any text back, then the bug does not appear. |
Expected behavior
Updating the alignment for a paragraph block should always update the alignment of the cursor and placeholder (if the placehodler is visible).
