com.unity.textmeshpro@1.5.0-preview.4

## [1.5.0-preview.4] - 2020-01-31
## [2.1.0-preview.4]
## [3.0.0-preview.4]
### Changes
- Fixed Input Field issue where scrolling events could prevent OnEndEdit event from firing. See [forum post](https://forum.unity.com/threads/mouse-wheel-on-multiline-input-field-with-no-scrollbar-hangs-input-field-stops-event-firing.794607/) for details.
- Improved Input Field handling of Vertical Scrollbar in conjunction with the ResetOnDeActivation property. Using the Vertical Scrollbar no longer triggers OnEndEdit event.
- Fixed MissingReferenceException when deleting a TMP prefab that is part of a nested prefab. Case #1207793
- Improved handling of allocations of newly created text objects with large amount of text. As a result of these revisions, allocations will potentially be reduce by 10X. See #1205923
- Fixed potential Null Reference Exception with the TMP DropDown that could occur when using the experimental Editor "Enter Play Mode" feature. Case #1207915
- Fixed potential issue with the assignment of sub text object materials.
- Add support for hiding the soft keyboard for Switch in the TMP Input Field.
- Fixed incorrect Preferred Height when Word Wrapping is disabled on text objects. See [forum post](https://forum.unity.com/threads/incorrect-wordwrapping-preferredsize-textmespro-2-1-preview-3.812376/) for details.
- Fixed additional instances of TMP Resource Importer window being created when deleting the "TextMesh Pro" folder just after having imported them. Case #1205848
- Added public ITextPreprocessor textPreprocessor; property to allow setting the text preprocessor for a given text component.
