Plotly

Fixed
- Fix missing x/y `texttemplate` for `histogram`, `bar`, `funnel` and `waterfall` traces [[6069](https://github.com/plotly/plotly.js/pull/6069)]

Fixed
- Do not exceed layout font size when `textfont` is set to "auto" for `heatmap`, `histogram2d`, `contour` and
`histogram2dcontour` traces [[6061](https://github.com/plotly/plotly.js/pull/6061)]

Added
- Introduce horizontal colorbars [[6024](https://github.com/plotly/plotly.js/pull/6024)]
- Implement `legend.grouptitlefont` and `hoverlabel.grouptitlefont` [[6040](https://github.com/plotly/plotly.js/pull/6040)]
- Add `texttemplate` and `textfont` to `heatmap` and `histogram2d` traces as well as
`histogram2dcontour` and `contour` traces when `coloring` is set "heatmap" [[6028](https://github.com/plotly/plotly.js/pull/6028)]

Fixed
- Fix to discard negative values from `pie` chart post-aggregation instead of during summation [[6051](https://github.com/plotly/plotly.js/pull/6051)],

Added
- Add `texttemplate`, `textposition`, `textfont`, `textangle`,
`outsidetextfont`, `insidetextfont`, `insidetextanchor`,
`constraintext` and `cliponaxis` to `histogram` trace [[6038](https://github.com/plotly/plotly.js/pull/6038)]

Changed
- Bump `probe-image-size` module to v7.2.2 [[6036](https://github.com/plotly/plotly.js/pull/6036)]

Fixed
- Fix mapbox derived coordinate for Retina displays [[6039](https://github.com/plotly/plotly.js/pull/6039)]
- Fix interaction between `uirevision` and `autorange`. Because we push `autorange` and `range` back into `layout`,
there can be times it looks like we're applying GUI-driven changes on top of explicit autorange and other times
it's an implicit autorange, even though the user's intent was always implicit. This fix treats them as equivalent. [[6046](https://github.com/plotly/plotly.js/pull/6046)]

Fixed
- Avoid bar with text to jump when selected [[6043](https://github.com/plotly/plotly.js/pull/6043)]

Fixed
- Fix hover events in Shadow DOM [[6021](https://github.com/plotly/plotly.js/pull/6021)],
